Shrink Plastic: The Guide to Successful Creations

Shrink plastic, also known as "crazy plastic", is a magical medium for both young and older creatives. If you are wondering how to turn a simple drawing into a solid, durable, and shiny object, you are in the right place. The principle is simple: it is a plastic sheet that, once placed in a household oven, shrinks to about 5 times its original size while thickening considerably.

During the cooking process, the plastic will curl in on itself in an impressive way: this is normal! It always flattens out again once the shrinkage is complete. It is the ideal material for making jewelry, keychains, or custom magnets.
