The technique on this card was actually something I came up with, so that's probably the reason you have never heard of it before! Ha, ha! It's really simple, though. Just press a sponge into an ink pad and working from the middle of the paper to the outer edge, smear the ink with outward strokes. For example, with this one, I started by smearing a small yellow circle, then followed it with orange, pink, and purple rings. I really suggest letting the colors overlap. It adds so much character!
