Shrinky Dink Fun

Materials: Plain Shrinky Dink sheets, permanent markers, colored pencils, hole punches

I have a vague memory of Shrinky Dinks from early childhood, involving an avocado-green oven and those pre-printed Shrinky Dinks that require no more creativity than coloring books. But then I began seeing tutorials for using recycled plastic, and then I saw blank sheets in the local toy/science store and tucked them away for a Christmas gift. Today we finally took them out to play! We’re not breaking any new ground here, but it was new to us and totally fun, and we have lots of blank sheets left!

I’d pinned a tutorial for Shrinky Dink buttons a while ago, so I definitely wanted to try that out. All the kids love buttons, so they all wanted to make some as well. We also printed out a sheet of computer-created stars for tracing and had the ruler out for squares and rectangles. V, being the oldest (and the most deliberate), decided ahead of time what size he wanted his finished square to be and then did the math to figure out what size plastic to begin with. (The package says pieces will shrink to about 1/3 their starting size.)

This is our output, pre-shrinking:

The wow factor of putting these in the oven and peeking through the window cannot be overstated! It was seriously cool! We tried the toaster oven first, but it just didn’t seem hot enough, plus we couldn’t fit much in at a time, plus we couldn’t all see, since it’s on the counter. Conventional oven is the way to go.

I realized afterwards that I made more pieces than the kids. Oh, well. (Did I mention how fun these are?!) Here are the kids’ creations:

V's creations

V wanted to re-create his stamp as a pendant for either a necklace or a key chain. Once he saw how much fun the rest of us were having with buttons, he made one, too.

N's creations

N wanted to make a star magnet and ended up with a smaller one than he’d counted on–but it still works as a magnet just fine (I cut a small square of self-adhesive magnet strip for the back). He had a hard time envisioning what 1/3 would look like. He really enjoyed making buttons, too.

G's creations

G does her own thing! She began with a the big button template (made using a 1 1/2″ hole punch, with the smaller holes punched with a normal hole punch), then colored on a rectangle, then punched a 1″ hole out from that, then had her brother add button holes to it. She also happily helped us count to 30 (the number of seconds you leave them in the oven after they flatten back down, to set them) and 15 (the number of seconds you leave some folded-up paper on top of them to keep them flat while they cool).

And here’s our total output of Shrinky Dink creations, after shrinking~mine are included in this photo, too.

I’ll have to experiment to see if the ink we used (permanent ultrafine Sharpies) will hold up to laundering, so we know whether these buttons can be used on clothing or are merely decorative. N is thinking about a career in button design*, so if that’s the case, I’ll need to make sure he has the right ink. And I may join him in his business venture, because this is the most fun I’ve had using the oven in quite a while!
