Homemade Shrinky Dinks From Recycled Plastic
Beware- if you read this you will start compulsively checking plastic containers to see if they can be made into homemade shrinky dinks! You might remember making shrinky dinks as a kid.
They seem kind of magical and when I discovered there are ways to make shrinky dinks at home using #6 plastic, I started keeping my eye out for possible containers.
When I found a cracker container with a number 6 on it (my first #6 find!), I wondered if I could make homemade shrinky dinks with rippled plastic.
I started experimenting- sometimes it's worth it to spend a little time experimenting before getting the kids involved. I rifled through my recycle bin and grabbed a few other containers just in case they would work. Soon I had determined:
- Number 1 plastic shrinks a little, but not much and also sometimes just turns white and curls – it's not a good material for DIY shrinky dinks.
- I read that foam is #6 plastic so I gave this a try with craft foam- sure enough, it shrinks like mad too. It does not, however get stiff.
- Meat trays from the deli are number 6 as well – and they are thick enough to make a shrinky dink.
- The #6 plastic with the ridges has a pretty neat effect when made into a shrinky dink. I like that it adds a texture to the little beads.
Here's How We Made Homemade Shrinky Dinks

Supplies:
- #6 plastic from your recycle bin
- Sharpie markers
- Hole punch
- Scissors
- Tin foil or parchment paper to line a cookie sheet for baking them on.
- If you wish to shrink these outside to avoid any fumes, a toaster oven you can use for crafts.
We cut out squares and heart shapes from the plastic container to decorate. Each piece we hole punched, and then colored with permanent marker before shrinking in the oven.
More Detailed Instructions:
1. We cut pieces from plastic containers and punched holes in them so that we could use them as little charms on necklaces or earrings. The plastic I used came from a cracker container. I also tried using a Styrofoam tray.
2. We decorated our plastic pieces using colorful Sharpie markers.
3. We put our creations in the oven at about 350ºF. I put them on a baking tray on parchment paper, but you could make a tray out of tin foil too.
- After about a minute- oh no! They're curling!
- After about two minutes (maybe three?)- they uncurl, and that's it, they won't shrink any more.
To avoid and fumes you can take this kind of activity outside and use an aluminum foil tray on a gas grill use a toaster oven that you plug in outside.
I was worried about the fumes, and I did turn on the hood. I have since read a better idea in Jean Van't Hul's Artful Year: She takes this kind of activity outside and uses a tray on her gas grill to avoid any fumes. Another option to take it outside is to use a toaster oven.
It's fun to recyle plastic pieces this way, but I've also discovered that it's not too expensive to just buy a kit or a pack of shrink plastic sheets.

More Ideas From Readers About Shrinky Dinks:
- I was looking for a way to make shrinky dinks for my Girl Scout troop to add to their homemade snow globes. I found that you can buy 8?x10? #6 plastic sheets at Home Depot for $2 a sheet. I love the recycled idea better, and from now on we will be using recycled plastic. However, if you are in a bind and “need” it quickly, the sheets from Home Depot worked GREAT!!
- Styrofoam cups can be colored with permanent markers and shrunk to make Barbie size doll’s hats. You can also cut into creative shapes and color them before baking.
- These are so fun! You can also stick metal pins through the plastic to make custom sewing pins.
