So one of the ideas in that book I bought was for painting on glass. While I didn't specifically use any of the patterns the book mentioned, I did buy some Iridescent Glass Paint by delta creative to see what would happen and here's the results!
It was a lot of fun to do, and I highly recommend it. Later, I'll try some of the specific ideas in the craft book, but for now it was good to just see how it went.
I think it would be interesting to buy a bunch of antique bottles, decorate them like this, and then set them in a window for the light to shine through.
Millions of ideas!
