These guys are little wood pieces glued together and painted. They have magnets on the back. I've learned that the key to making anything involving painting and a toddler is giving them ONE color at a time. Otherwise everything is one big brown blob! ;-) You could also give them to colors to mix, as long as the two colors are primary ;-) That green guy was the result of some fun mixing!
On a totally unrealated note... The powercord to my Macbook has failed me again. The first time I had Apple Care and it was replaced for free... but that has since run out - so I'm waiting on one from good ol' E-bay. won't have it until the middle of the week! Yikes!!!
