You know I love crows - and drizzles. I started with blowing the color outward in the direction of the wings and tail (like Val Webb shows on her blog. I wasn't thrilled with the outcome, whether I blew across the paper or used a straw, so I just tilted the paper, dropping water at the top of the pigment (with a brush full of clean water) and let it flow out out out. I'm liking this one and can see doing others using this technique.
