I scratched this 'Blue Chimp' out yesterday after getting home from my Ampersand Art Scratchboard demo at Jerry's Artarama here in Austin. This is a 5"x5" clayboard black scratchboard. Haven't used this size before...and I had some influence from the folks in the class regarding laying color on and taking it back off. The blue is Liquitex acrylic ink that I brushed on and then used a paper towel to remove. Fun stuff. I'll post images from the demo here in a bit.
