Ok mom's (well, dad's, meme's, nana's, or anybody that loves art supplies) I am obsessed with these Crayola Crystal Effects Window Markers!
I was shopping for Clara Jane's B-day and found them at Wal-mart in the children's art supply section. You can color a design on any window or glass surface and the colors slowly, magically crystallize before your eyes! They go on almost transparent and then start crackling and become more opaque (almost like a stained glass effect.)
They are less than $4.00 for a pkg of 8 different colors, and they are washable. Boy am I gonna have fun with these---I got 2 packs---one for me and one for Clara. Don't tell her, it's a secret.
Go get some!!! Your kids will love them--and so will you!
(You're welcome Crayola---I'm off to go doodle.)
