Autism wiggly trivet

This is a crocheted wiggly trivet using seven colors of size 10 crochet thread.
It's a "frame" of puzzle pieces surrounding a puzzled heart in the center.
(Please click on the photos to enlarge them).

Each puzzle piece is shaped like a person. (Except for some inside the heart. I couldn't make all those the person shape).

The last photo is of the back. If you make one of your own this will help you.
