About Layering I thought you
I thought you might like to look at a site I went to last night on Wet Canvas. It was by Makitmama re: Crash Course in Layering. It had a lot of information which I am going to use myself so I hope it helps you as well. Just go into Wet Canvas site & check through until you find that write-up which is quite long. I would print it out in case it disappears or save it into your glass file until you can print it.
Best of luck Tosca
