Crafting Memories: DIY T-Shirts at Your Next Slumber Party
Updated September 2026
A great sleepover activity should be fun, easy to organise and give the kids something to remember the night by.
That’s exactly why DIY T-shirts work so well.
They give everyone a chance to be creative, they keep the group busy without needing screens, and each child gets to take home a personalised keepsake from the party.
Whether your sleepover is being held in indoor teepees, an open-style cabana or a Bell Tent, a T-shirt decorating station can be a simple way to add something extra special to the celebration.
Here’s how to make it work.
🎨 1. Keep the Setup Simple
You don’t need a full craft room.
Choose a table or floor area with enough space for everyone to work comfortably and cover the surface with:
• A plastic tablecloth
• Newspaper
• Butcher’s paper
• An old sheet
If you’re using paint, it’s also a good idea to have wipes or damp cloths nearby.
The easier the cleanup, the more enjoyable the activity will be for everyone!
👕 2. Choose the Right T-Shirts
Plain cotton T-shirts are usually the easiest option for decorating.
White works particularly well because colours show up clearly, but black or coloured shirts can also look fantastic depending on the theme.
Before the party, find out each guest’s size so you’re not guessing on the night.
You could also use:
• Pillowcases
• Tote bags
• Pyjama tops
• Calico bags
if you’d like something a little different.
✏️ 3. Gather Your Supplies
You can make the activity as simple or elaborate as you like.
A basic DIY T-shirt station might include:
• Fabric markers
• Fabric paint
• Stencils
• Paintbrushes
• Letter templates
• Fabric-safe stamps
• Sponges
• Aprons or old shirts to protect clothing
You really don’t need every craft supply imaginable.
For many groups, fabric markers and a few stencils are more than enough to create some brilliant designs.
✨ 4. Choose a Theme — or Let Them Go Freestyle
You can tie the designs into the birthday theme or let everyone create whatever they like.
Ideas could include:
🌸 Boho
⚽ Sport
🎮 Gaming
🌈 Rainbow
⭐ Stars
🎤 Music
🪩 Disco
💖 Friendship
🐶 Animals
✨ Initials and names
For a friendship-themed sleepover, guests could even sign each other’s shirts or write little messages around the design.
That turns the shirt into a genuine keepsake from the night.
🖍️ 5. Put Cardboard Inside Each Shirt
This is one simple trick that can save a lot of frustration.
Slide a piece of cardboard inside each T-shirt before decorating.
It helps:
• Keep the fabric flat
• Stop markers or paint bleeding through to the back
• Give children a firmer surface to draw on
An old cereal box cut into rectangles works perfectly.
💡 6. Give Them Some Inspiration
Some children will immediately know what they want to create.
Others may stare at the blank shirt wondering where to begin!
Have a few simple ideas ready, such as:
• Their name or initials
• A favourite quote
• Stars, hearts or lightning bolts
• Their favourite sport
• Matching friendship designs
• Birthday-themed artwork
• Handprints
• Simple patterns
You could even print a few design inspiration sheets and leave them on the table.
🤝 7. Make Matching Friendship Shirts
For a fun group activity, create one small element that everyone adds to their shirt.
It could be:
• The birthday child’s initials
• The party date
• A small star or heart
• A friendship symbol
• The same phrase somewhere on every shirt
Each child can then personalise the rest of their design.
The shirts still feel individual, but they have one little detail connecting everyone from the sleepover.
🎶 8. Add Some Music
Crafting and music are a great combination.
Put on a party playlist while everyone creates their shirts and let the activity become part of the social side of the sleepover.
Kids will usually spend just as much time chatting and laughing as they do decorating.

🍕 9. Make It Part of the Night
DIY T-shirts don’t need to become the entire party.
They work well as one activity within the sleepover.
For example:
Arrive & settle in
→ Decorate T-shirts
→ Pizza or dinner
→ Games
→ Movie
→ Sleepover
Starting the shirts reasonably early also gives fabric paint time to dry before the kids need to take them home.
⏰ 10. Allow Plenty of Drying Time
This is especially important if you’re using fabric paint.
Check the instructions on your chosen product before the party, as drying and heat-setting requirements can vary.
If you’re worried about wet paint, fabric markers may be the easier choice.
Have somewhere ready to place finished shirts flat or hang them while they dry.
📸 11. Take a Group Photo
Once everyone has finished, get the group together wearing or holding their designs.
It makes a gorgeous birthday photo and shows off all the different creations.
You could even recreate the same picture a few years later and see how much everyone has grown.
👗 12. Have a Mini Fashion Parade
If the group loves performing, let everyone show off their finished designs.
Put on some music, create a pretend runway and let them model their shirts.
You don’t need judges or prizes.
Just make it silly and fun.
For quieter groups, simply laying all the designs out together for a photo works just as well.
🛍️ 13. Turn the T-Shirt Into the Party Favour
One of the best things about this activity is that the finished T-shirt can double as the guest’s take-home gift.
That means you may not need to organise a traditional lolly bag or separate party favour.
The children leave with something they made themselves — and something that reminds them of the celebration.
💙 Why DIY Activities Work So Well at Sleepovers
Sleepovers don’t need constant entertainment.
A creative activity like decorating T-shirts gives kids something to focus on while still leaving plenty of room for conversation, laughter and friendship.
There’s no pressure to be “good” at it.
Everyone gets to create something that reflects their personality.
And often, the funny little mistakes and unexpected designs become the parts they remember most.
🎲 Looking for More Sleepover Activities?
Slumber Wonderland also offers FREE downloadable sleepover games that kids can play together.
They’re easy to print and have ready for those moments when the group wants something else to do.
Pair them with your T-shirt activity, favourite music, pizza and a movie and you’ve got plenty to keep everyone entertained without over-planning the night.
✨ Creating Memories That Last
The best party keepsakes aren’t always the expensive ones.
Sometimes it’s a T-shirt covered in colourful doodles, friends’ names and a slightly wonky design that ends up being treasured the most.
At Slumber Wonderland, we love creating spaces where children can slow down, connect with their friends and make memories together.
We create magical sleepover experiences for families throughout Wollongong, the Illawarra and surrounding areas, from individual indoor teepees and open-style cabanas to backyard Bell Tent adventures.
So gather the markers, choose the T-shirts and let the creativity begin.
The kids may arrive for a sleepover…
but they’ll leave with something that reminds them of it long afterwards.
