I saw a video on Stamp TV from Gina K a few months ago on crayon resist. I LOVE this technique! It's so easy and there's always a wow factor when you see the image appear as you add color! I just wish you could buy a whole box of white crayons!!
Anyway, here is one of the many cards I've done with this awesome technique! Stamps are all Hero Arts, inks are Memento and Distress.
