I ordered some tshirts from Crayola.com that you can draw on with washable markers. The art washes out when you wash it. Well, we used them for our first day of school and I've been thinking about how we would use them again. I just thought of a neat thing to do. DS is learning the letters of the alphabet and numbers and we do a letter/number of the week. I could use the tshirt to reinforce the letter or number of the week!!! I'll try that next week and see if it helps teach him his letters/numbers. BTW, crayola.com had these shirts on sale/clearance if you want to view them. You can actually use washable markers on any cotton tshirt and it should wash it. However, these happen to have a thick coating?? on them inside the border. It was very easy to write on it and draw on it. Anyway, just had to talk about my discovery, lol!
