I’ll answer some questions from the comments on my previous shrinky rings post before I get started, and add more hints and tips throughout the tutorial.
Shrink plastic, for the uninitiated, was originally marketed as a toy for kids. It starts life thin and flexible. You draw on it and then bake it in the oven, and it shrinks to become about 1/3 of the starting size, but 9 times as thick. This thickness makes it strong and hard. It will not bend after baking, so if you try to pull your ring open, or stand on it, it may snap, but it is strong enough to withstand regular use as a ring.
The last step (bending the ring into shape) is the most difficult, so I highly recommend that 1) you read through all the instructions before starting, and 2) practice on a blank piece of shrink plastic so you can get a feel for it and test your size and bending technique before putting too much effort into your design!
