Stained Glass Window Paints

I have had a packet of window paints in the cupboard for a while. It seems like it is something that is too hard for the children to manage on their own without extensive assistance from me. I had a little more time than usual this week so thought I would give it a go. I traced the design from the book with the black paints and let it completely dry. Once it was dry then I let the children loose with the paints. My only stipulation was they could only use one paint at a time and needed to let it dry before moving on. Well, it is a good thing the paint dried very quickly or the first photo would have been as far as the picture developed.
