Here's something a little different than what I normally do... a Celtic-inspired tree mandala!
I created the twisted vine motif using Adobe Illustrator (it took me forever to figure out how to do it!) and I hand-drew the tree, leaves and swirls. I printed it out and colored the tree mandala using Prismacolor colored pencils, Copic markers, Sakura gel pens and Fiskars gel pens.
The line art for this drawing will be included in my upcoming "Nature Mandalas Coloring Book" which will be published in September 2014 by Fox Chapel Publishing.
