I recently bought a package of Shrinky Dinks and the kids and I couldn't stop creating things. If you haven't tried it you should. You start with thin sheets of plastic and then you draw on them with either permanent markers or pencil crayons. Some shrink plastic you buy is shiny on both sides and therefore pencil crayons don't work - but if you rough up the plastic with sandpaper the pencil crayons will work. After you colour your picture cut it out and put a hole in it before you shrink it.
Lilo made 2 little hockey players. She started by drawing the picture on paper first and then putting the drawing under the plastic and taped in place while she drew and coloured the picture on the plastic.
Another thing we figured out was that colours get darker when they shrink as well. Colours turned out nicer with pencil crayons versus permanent markers - see photo above. Also be careful cutting things out - the plastic can rip while cutting and also be careful when they are shrunk as thin pieces can break off (poor one armed hockey player)
I also had fun and made a super awesome Shrinky Dink - I'll show you tomorrow.
