The Amazing Shrinky Dink Ruler

I’m making a luchador necklace for Eli (with big manly links. It’ll be tough!), but I lost the original sketch of the masks. No problem, I could recreate those, but I couldn’t remember how big the shrinky dinks were before I shrunk them in the oven. So I got out a ruler and applied my mathematic skills.

It turns out I have no mathematic skills.

I now have five beautiful 3 inch long luchador masks. Okay, they will make very nice fridge magnets (although I think they should be backed with another layer of plastic for stability), but they're way too large for a necklace.

Clearly I needed some kind of tool.

I made one.

Now I don’t claim to be the only one to have thought of this, but it was an original idea for me. After all, bats and birds both developed flying abilities wholly separate from one another.

I took a scrap piece of Shrinkydink and laid a measuring tape next to it.

I then marked off all of the measurements on the plastic.

Then I baked it in the oven, shrinking it down. All shrinky dinks of the same brand should shrink to the same proportion.

Now I can tell how big a shrinkydink was before I baked it!
