Beware- if you read this you will start compulsively checking plastic containers to see if they can be made into homemade shrinky dinks! This is what happened to me when I first read about homemade shrinky dinks. The poster said to use number 6 plastic, and it turn out that’s a little bit hard to come by.
The other day I found a cracker container with a number 6 on it. My first #6 find! I wondered- could I 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 seem to be 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:
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.

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.
I was worried about the fumes, and I did turn on the hood, but I didn’t really smell bad. In fact I think I got more fumes from the permanent markers than from the plastic.
I discovered that it’s not too expensive to just buy a Shrinky Dinky kit: Make Your Own Shrinky Dinks, but as for me, now I’m on the look out for more plastic I can recycle into my homemade shrinky dinks!
