My interpretation of a zombie, that also has to remain cute, because she is, after all, a Lacy Sunshine digi, is this:
Skin: Copic markers colors V000, V01, G000, G00, BV000
Eyes: BG000, B12, B14
lips: R21, R22
Hair: E50, Y21, YR24
Clothing: V12, V15, V17
YR00, Yr02, YR07, E15, E18
There's an anything goes challenge happening on the Lacy Sunshine blog, so come join the fun! I have 2 Facebook groups for you to check out, too. There's the Lacy Sunshine Color N Craft Community and the Coloring Without Boundaries Facebook Group. Both are wonderful, supportive communities to show your work, get inspired, and hear of sales and news.
