nice looking patterns. I really like the last feeding profile.
I draw mine but I normally do not keep them. I know I should spend more time on the pattern part but I normally work from 1 or 2 patterns or just take a photo I like into the shop and work it out on the foam block. Doing it that way gets me in trouble sometimes but foam is cheap. If I'm doing a cork or wood decoy, I spend more time on the pattern.
