I did do a quick and fun project over the weekend. I saw it on Creative Juice, the DIY Network show. I always wanted to try it, even bought the cookie cutters and liquid dishwasher soap, but somehow never managed to do it. (Nothing like a new blog to get you to be creative.) Anyway, you dip cookie cutters into liquid dishwasher soap. I used Cascade. Then stamp onto a t-shirt that has cardboard layered inside to protect the back. Dark color shirts work best. You let it set for a half an hour, and then wash and dry the shirt.
Here is a close up of the shirt.
This would be a great project to do with older children. The liquid dishwasher soap can be a bit messy and does contain bleach. It would be a nice alternative to the Tye-dye t-shirt.
