I have a Christmas project this week using Reindeer Kitty from Whimsy Stamps. I wanted to work on fur texture so I pulled up some pictures of cats and settled on a common tabby. I started with the lightest color and worked towards the dark. Then without blending, I tried to pull in some of the lighter colors where it was needed.
Here are the Copic markers I used on Reindeer Kitty:
YG01, 23, 63
Y21, 26, 28, YR23
E04, 42, 43, 44, W5, 9
R12, 05, 46, 59
This and other Whimsy Stamps are available at Little Miss Muffet Stamps.
