I have been playing with some new transfer techniques. Waxpaper works (varies with brand) as well as a combination of soap and turpentine.
When Sandra and I were writing the book we would sit around and just try and figure out what could get an image to transfer. Ironing an image to plastic wrap was my big idea - and worked so well.
This piece, Splish Splash, started with this great image of a little girl with a hose that made such a great line.
