Have to say had a bit of a challenge with the canvas technique as I do not own any sticky back canvas and thought (somewhat foolishly it seems) that I could use the offcut of artist canvas I got from a local art store. Unfortunately did not know it was not primed and could not work out why it was not working for me. (Insert trumpet sounds here like the riding to the rescue sort) Along comes a good friend who points out the Monte Marte Canvas pad is the same a sticky back canvas, though not as thick as the artist canvas it is also pre primed. It worked and I was able to pull off the resist technique without a hitch upon using the Canvas Pad.
Also wish my rock candy crackle paint was a little less watery. However onto the tags
