Jennifer McGuire showed this oldie but goodie technique. I do like it better than smooshing because it allows for more brilliant color. Letting the block sit on the watercolor paper for five minutes really does make a difference. I played with this technique all afternoon...making me realize a few more acrylic blocks would be good. *smile*
I used Distress Inks but Jennifer mentioned you could probably use Tombow markers as well. I'll give that a go another day.
