Homemade Shrinky Dinks

You can use old takeout containers to make homemade Shrinky dinks that are just like the store-bought film you get at the craft store. It’s environmentally friendly to use something you already have around the house instead of throwing it into the landfill.

I always loved making Shrinky dinks when I was a kid. I remember standing by the toaster oven with my sister watching the little plastic sheets curl up and melt. Such a fun thing to make. It seemed magical to me and these work just the same way. Let’s see what you need to get started.

Used takeout containers for homemade shrinky dinks

Shrinky Dink Plastic

Clear plastic takeout containers are usually not recyclable. Here where I live, we can only recycle number one and two plastic. You may have more options where you live, but this activity is fun too and you can still recycle the scraps for shrinky dink plastic.

Check the little triangle on the container and see if you can find one with a 5 or a 6. I don’t get much take out but several people bring me their containers to use with the kids and I grab out the ones we can use for shrinky dink plastic. Most of the ones I see around here are number 6.




Shrink Art

The next thing you need to decide is what kind of medium you will use to decorate them. Sharpies work great, but who wants to let their kids loose with sharpies? If that’s you, go for it! But for me, I need a less permanent option. On our homemade Shrinky dinks, we used three options to show you.

Example number one is sharpie.

Then example number two is colored pencil.

Example number three is roll up crayons.

Once they shrink down, they all look great as you can see.

Open Ended Art

I stink at freehand cutting, but if you are creative with that or have some large punches, you can cut out your own shapes like I did here. I love the idea of letting kids do open-ended art, but I find that parents like product art much better than process art, so I try to show the kids both. There is good learning in product art too such as how to follow instructions. With open-ended art, kids can be free to be their own kind of creative.

I just let a child have a piece of the plastic and a few roll up crayons and go after it. Then I attempted to cut it into a heart shape. You could lay the sheet on a coloring book page or some of our free printable patterns and first draw a heart onto the sheet. Then when you cut it, it would turn out better than my free handed one.

Let the kids make any designs they wish and then cut them into shapes for them after. This makes a wonderful product but they still get to be creative. If your kids are older, let them cut them out themselves. That would really be unique and creative.

DIY Shrinky Dinks

Once you have selected your medium, it’s time to make the homemade Shrinky dinks.

Step 1. Cut the flat parts of the plastic out of your container (or grab your sheet of store-bought plastic)

Step 2. Take fine sand paper and lightly scratch the entire surface of the plastic so it’s rough and will hold the color of your medium.

Step 3. Wipe the plastic lightly and choose your design.

Step 4. Decorate your plastic on the rough side.

Step 5. Cut out your design.

Step 6. Punch a hole in the top of the design.

Step 7. Bake at 350 for about 5 minutes or until your items are flat. (you may want to line your baking tray with parchment or aluminum foil) (you may also want to take a toaster oven outside to avoid fumes inside, or preheat the grill and shrink them in there. We didn’t smell any fumes when we made them but better safe than sorry!)

Remember to make sure you punch a hole in your item BEFORE you shrink it if you want it to have a hole in the end. I used to forget that as a kid. I’m sure you could drill a hole, but punching before is far simpler.

    i have old plastic folders that my daughter used for school. they are to pretty to throw i was wondering if i could use those to make shrinky-dinks

    • Christina says:

      I’m not sure what kind of plastic they are, I would imagine they wouldn’t work for shrinky dinks, but maybe you could repurpose them another way such as cutting out shapes and punching a hole to make necklaces or keychains. Something that you don’t have to melt. It would be fun to try!

  2. Tracey says:

    First, let me say I love the cute ideas you share. I was researching other plastics you could use to make Shrinky Dinks as # 6 is harder to find. This is what I found out, PS 6 Plastic, is a type of Styrofoam that releases toxins into the air when heated. You might want to explore different types of recyclable plastic at a lower heat.

    You can get 10 sheets of Acetate for $5.99 @ Walmart.

    There are other websites as well.

      Yes, that’s a good reason to use a toaster oven and do it outside. You can never be too careful with plastic. Thanks for your input and for checking out the article.

    Several years ago I volunteered to teach arts and crafts to two classes of 5th Graders. It was fun. This is one of the projects we made. The kids loved it…so did I!!!

    I didn’t know that you could do this! I think I’d definitely opt to do it outside, but what a creative idea!
