You’re halfway through tidying a child’s room, setting up the garden for a birthday, or trying to make a rented flat feel less temporary, and the wall still looks bare. Rainbow bunting is one of the fastest, most forgiving crafts you can make, and it changes the feel of a space in minutes. You can keep it gentle with washed-out fabrics, go bold with paper and paint, or make it durable enough to live outside for a season.
This guide focuses on DIY rainbow bunting you can finish: ten easy designs, practical templates you can copy, and styling ideas for home, kids’ rooms and the garden. It also covers what usually goes wrong, such as sagging lines, curling paper and colours that clash, and how to fix it without starting again. The rainbow bunting trend for 2026 is straightforward: people are using colour as a mood-lifter at home, but choosing more tactile, handmade-looking finishes rather than shiny party plastics.
Choose the right bunting style for where it will hang
Before you cut anything, decide what the bunting needs to tolerate. Indoors, almost any material works, including paper and lightweight fabric. Outdoors, wind and damp change the brief, so you’ll want sturdier flags, fewer tiny parts, and a line that won’t stretch and droop.
It helps to be clear about the job the bunting needs to do, because that’s where people get stuck in a loop of re-making. If it’s for a one-day party, you can accept tape, paper and quick knots. If it’s for a nursery corner you’ll see daily, you’ll probably prefer fabric flags with neat spacing and a calmer palette. Garden bunting needs a different approach again: if you want it to survive a few weeks, choose materials that won’t dissolve or crack, and plan where it can be taken down quickly if the weather turns.
In short: paper or light fabric suits indoor bunting, and smaller flags work well on shorter spans. Outdoor bunting needs a stronger line and larger flags, and each length should stay short enough that it doesn’t sag under its own weight.
Materials, tools and colour planning that won’t overwhelm
You do not need a big craft haul to learn how to make rainbow bunting. What you need is one base material, one method of attaching flags, and a colour order you can follow without thinking too hard. That’s the difference between finishing in an evening and having a bag of half-cut triangles that never becomes anything.
For fabric bunting, cotton or polycotton is easy to handle and forgiving to sew. Felt doesn’t fray, so it’s good for no-sew options, but it can look heavy if your room is small. For paper bunting, cardstock holds its shape better than thin printer paper, and it’s less likely to curl if you hang it in a warm room.
Colour planning is where “rainbow” can go either playful or chaotic. Decide early if you want a classic red-to-violet rainbow, a pastel rainbow, or a modern rainbow that swaps in neutrals, such as cream, tan or warm grey, between brights. If you’re coordinating with a child’s room, pick one dominant colour already in the room (for example, a rug or bedding) and make sure it appears at least twice in the bunting run so it feels intentional.
Keep your joining method simple. Sewing is strong and neat, but it’s not the only option. Fabric glue, iron-on hem tape, stapling over a ribbon, or threading flags onto a cord all work if the bunting is not under tension. For paper, double-sided tape is quick, and a glue stick is tidy, but allow time for it to dry fully before you hang it.
Easy templates you can copy without special equipment
Most bunting templates are variations on three shapes: a triangle, a swallowtail with a V-notch at the bottom, or a rounded pennant. Using one shape across the whole run looks calmer; mixing shapes can look busy unless you keep the colours restrained.
Template 1: classic triangle
Cut a rectangle, fold it in half, then cut a diagonal from the fold down to the opposite corner to create a symmetrical triangle. This fold-and-cut method keeps your flags consistent even if you don’t have a ruler to hand. If you’re using fabric, add extra around the edges if you plan to sew seams; if you’re using felt, you can cut and go.
Template 2: swallowtail pennant
Start with a rectangle, taper the sides slightly as you cut downwards, then cut a small V at the bottom. Swallowtails flutter well outdoors and read as festive even in muted colours. They also hide minor wonkiness because the notch draws the eye.
Template 3: rounded flag
Use a plate or a small bowl to round the bottom corners. Rounded shapes feel softer in bedrooms and playrooms, and they suit pastel rainbows well. They also reduce sharp points that can crease or curl if you’re using paper.
If you want letters or simple shapes, keep the motif large enough to read from where you’ll stand. Tiny details disappear once the bunting is moving, and they add time you may not have. As a general approach, make one hero element every few flags, such as a heart, star, initial or small stitched patch, and leave the rest as plain colour blocks.
Ten easy handmade designs for DIY rainbow bunting
These designs are built to be achievable with basic tools. You can adapt any of them for a child’s room, a mantelpiece, a garden fence, or a party table. The trick is to pick one design and finish it before you add extras, since half-finished bunting tends to become an “almost” project.
1) Two-layer fabric triangles with pinked edges
Cut two triangles per flag, place wrong sides together, and use pinking shears around the edges to reduce fraying without turning hems. Stitch a straight line near the top to attach each flag to a ribbon or bias tape, or glue if it’s for light indoor use. This gives you a finished look without fiddly corners.
2) Felt rainbow bunting with cut-out shapes
Felt is ideal if you’re avoiding sewing. Cut solid flags in rainbow order, then cut simple shapes, such as stars, circles or clouds, in white or gold felt and attach them with fabric glue. Keep the shapes chunky so the edges stay crisp.
3) Paper bunting with painted brush-stroke colour
Cut white cardstock flags, then paint broad stripes of colour across each one. This looks handmade in a controlled way, which fits the craft-texture look favoured over glossy finishes. Let the paint dry flat before folding the top over the string, otherwise it can crack at the fold.
4) Scrap-fabric patchwork flags
Sew or glue together strips of leftover fabric into a rough patchwork, then cut your flags from the assembled piece. Patchwork is forgiving because the eye expects variation, and it’s a practical way to use odd leftovers. Keep the top edge straight and reinforce it, because patchwork can pull apart if it’s only attached at a few points.
5) No-sew ribbon bunting on a cord
Cut lengths of ribbon in rainbow colours and tie them onto a cord with simple knots, spacing them closely so they form a dense fringe. This is fast and works well for stair rails, bed frames, or garden pergolas. Use ribbons that won’t bleed colour if they get damp, or keep this one indoors.
6) Mini rainbow bunting for shelves and windows
Make small flags and hang them on a shorter line for a bookcase, window frame, or over a changing table. Mini bunting looks tidy if the flags are evenly spaced, so measure or mark the line first. If you’re in a rented home, this is easier to hang with removable hooks than a long, heavy run.
7) Reversible bunting with two colour stories
Make each flag double-sided with different colours on each side, then hang the bunting so you can flip sections later. One side can be a bright rainbow for parties and the other can be a muted, everyday rainbow. This is useful if you share a space and want a quick reset without a discussion every time.
8) Stencilled rainbow bunting with simple icons
Cut plain flags in one colour, such as cream or pale grey, and stencil rainbow icons onto every other flag. A repeated motif looks calm in a bedroom and stops the bunting feeling like a toy aisle. Use a dry brush technique so paint doesn’t seep under the stencil edges.
9) “Soft rainbow” bunting with ombré ordering
Instead of repeating the same seven colours, use multiple shades per colour family and order them from warm to cool. This makes the bunting look more like décor and less like a party decoration. It’s also forgiving if you can’t find exact rainbow matches in your fabric stash.
10) Outdoor-ready laminated paper bunting for short-term use
If you want the look of paper outside for a day or two, heavier paper plus lamination or clear protective sleeves can help it resist light damp. Keep the run short, hang it under cover if you can, and take it down promptly if the weather changes. This is a good compromise when you want bright colour but you don’t want to sew.
A straightforward step-by-step for neat, sturdy bunting
This method works for fabric or paper because it focuses on the two things that matter: consistent flags and a strong top edge. You’ll make decisions once, then repeat them, which keeps the project calm and finishable.
Step 1: measure the space and choose the line
Decide where it will start and end, then add extra length for tying or hooking at each end. If you are hanging across a walkway or garden path, keep it high enough that nobody brushes into it. Choose a line that suits the weight of your flags, because stretchy string sags over time.
Step 2: pick your flag count and spacing
Lay your line on the floor and place a few sample flags along it until it looks right. Denser spacing reads fuller; wider spacing looks lighter and more like décor than a party. Mark the line with small pencil marks or tiny bits of tape if you want even gaps.
Step 3: batch cut your flags
Cut one perfect flag first and use it as the template for the rest. Stack paper to cut multiple layers, or fold fabric if it’s not too thick. Keep all your top edges aligned, because that is where the bunting’s neatness comes from.
Step 4: reinforce the top edge
For fabric, you can fold the top edge over the tape or ribbon and stitch. For paper, fold the top edge over the string and secure it firmly with tape or glue, and press the fold with the back of a spoon so it holds. This is where bunting fails if you rush; a weak top edge means flags slip and bunch together.
Step 5: attach flags from the centre out
Start at the centre of the line and work towards each end so the spacing stays balanced. If you start at one end, you often reach the other side with a pile-up of flags and no room to adjust. If your rainbow order matters to you, write the colour sequence on a scrap of paper and tick off as you go.
Step 6: hang it, then adjust tension and drape
Hang the bunting loosely first, check the drape, then tighten it. If it sags too much, shorten the span by using an extra hook in the middle or splitting it into two lengths. Give it a day indoors to settle, because some lines stretch slightly after hanging.
Hanging rainbow bunting safely indoors and outdoors
Most bunting problems are hanging problems rather than making problems. A good hang looks intentional; a bad hang makes even beautiful flags look messy. Indoors, removable hooks, small nails, curtain poles, or picture rails can all work depending on your walls and whether you rent.
In a rented home, prioritise methods that can be removed cleanly. Removable adhesive hooks are useful if the surface is smooth, clean and dry, but they can fail on dusty paint, textured walls, or cold external walls. If you can, test one hook with weight before you commit to the whole run. For bunting over beds or cots, keep it well out of reach and avoid anything that could fall; if you’re unsure about placement, ask a health visitor or follow local safe-sleep guidance for your country.
Outdoors, think about wind direction and friction points. Bunting that rubs against brick, rough timber or metal edges will wear quickly, so use a spacer, such as a short loop of cord, to keep it away from sharp corners. If you’re using hooks, choose ones suited to the surface, and avoid hanging anywhere near power lines or where it could tangle around gates.
If you need to get height, use proper equipment and stay within your confidence. A step stool on uneven ground is an easy way to end up with a sprain. If it needs a ladder, a second adult is sensible, and if you can’t anchor it safely, bring the bunting down to a reachable height or ask someone who can help.
Styling ideas for kids’ rooms, home and the garden
Rainbow bunting looks best when it relates to the rest of the space, rather than fighting it. If you’re styling a child’s room, consider the view from the doorway and the bed, since those are the angles you see most. A line across a bookcase, over a reading nook, or along the wall above hooks for dressing-up clothes makes the bunting feel part of the room’s routine, not just decoration.
For shared family spaces, a calmer approach prevents the bunting becoming a point of friction. If one person loves bright colour and another finds it visually loud, treat it like any shared decision and agree boundaries. You can keep the rainbow but reduce the intensity by choosing softer tones, using smaller flags, or limiting bunting to one area rather than every wall.
In the garden, bunting can define zones. A run between two fence posts can mark a play area, a short line over a table can set out a party corner, and a longer line along a fence can pull attention away from scruffy patches. If you have plants, let them be part of the styling, but keep bunting away from thorns and anything that will snag fabric.
The look many people want in 2026 leans towards layered colour rather than a single harsh stripe. Pair bunting with textured materials such as woven baskets, natural wood, and simple ceramics, and it reads as a décor choice rather than a one-off party item. If you want it to look grown-up in a hallway or kitchen, keep the flags smaller and the colour palette slightly dusty rather than primary.
- Over a doorway to frame the room without taking wall space.
- Along a shelf edge with mini flags so it looks built-in.
- On a fence with short runs that can be taken down quickly.
- Across a mirror so it doubles the colour and light.
Common mistakes that cause sagging, curling and fraying
Sagging usually comes from a line that stretches, a span that’s too long, or flags that are heavier than you expected once they’re all attached. Fix it by adding a central support point, shortening the run, or swapping the line for something stronger. If you’re tempted to pull it very tight to compensate, stop and reconsider, since tight lines can rip paper flags or distort fabric.
Curling is the classic paper-bunting issue. It can be caused by paint that hasn’t dried, glue that adds moisture to one side, or paper that’s too thin. You can flatten curled flags under books overnight, and you can reduce curling next time by using thicker paper and applying glue in a thin, even layer.
Fraying on fabric flags happens when you cut along a loose weave, skip finishing the edges, or wash the bunting. If you want bunting that lasts, either hem, zigzag stitch, use pinking shears, or choose felt, which doesn’t fray. If you already have fraying, trimming loose threads and adding a line of stitching close to the edge usually tidies it up.
Colour clashes are less about taste and more about proportion. If one colour looks wrong, try reducing how often it appears rather than removing it entirely. Repeating a colour in two smaller accents often looks better than one large block that dominates the whole run.
Care, storage and reusing bunting without a tangled mess
Storage is where bunting either becomes a reusable item or a bin job. Paper bunting should be stored flat or gently rolled; if you fold it sharply, it will keep the crease. Fabric bunting can be folded, but avoid crushing any glued embellishments.
A practical method is to wrap the bunting around a piece of cardboard or a wide ribbon spool, keeping light tension as you go. Secure the ends so it doesn’t unravel in the cupboard. If you have multiple bunting strands, label the spool with where it fits best, such as “window”, “garden fence” or “bedroom shelf”, because that saves time next time you want a quick change.
If the bunting gets dusty, fabric flags can often be gently vacuumed with a brush attachment on a low setting. Washing depends on materials and dyes, so check the fabric and any trims before you wash, and expect some fading over time. Outdoor bunting benefits from being taken down when you’re not using it, since constant sun and rain will shorten its life.
Reusing bunting also means being honest about what’s good enough. If a few flags are damaged, replace only those and keep the rest. Perfectionism is where many DIY projects stall, and bunting is meant to move, flutter and look lived with.
Frequently asked questions
How do I work out how many flags I need for rainbow bunting?
Lay your string or tape out on the floor and place a few sample flags with the spacing you like, then count how many fit in a set length and scale up. If you want a full look, use tighter spacing; if you want a lighter, calmer look, increase the gaps. Starting from the centre and working outwards makes it easier to keep the spacing even.
What is the easiest no-sew method for DIY rainbow bunting?
Felt flags on a cord are one of the simplest because felt doesn’t fray and holds shape well. Another quick option is ribbon bunting made by tying lengths of ribbon onto a line, which also packs away easily. If you use glue, give it proper drying time before hanging so the flags don’t slide.
How can I stop paper bunting from curling?
Use thicker cardstock rather than thin paper, and avoid soaking one side with paint or glue. Let painted flags dry completely before you fold the top edge over the string. If flags curl after hanging, flatten them under a heavy book overnight and reattach if needed.
Can rainbow bunting be used outdoors in a garden?
Yes, but plan for wind and damp. Shorter runs sag less, and sturdier flags and a stronger line last longer. If you want paper bunting outdoors, treat it as short-term and take it down if the weather changes.
How do I hang bunting in a rented home without damaging walls?
Removable adhesive hooks can work on clean, smooth surfaces, but they can fail on textured paint or dusty walls. Hanging from curtain poles, picture rails, shelves or existing hooks avoids wall damage entirely. Test one hook first with a bit of weight so you’re not picking flags up off the floor later.
