Feather Spiral Zentangle

This Zentangle was inspired from a picture of a wholecloth quilt I saw that was quilted in a spiral design. I love the use of feathers in quilting.  So I combined a spiral with a feather quilting design for this Zentangle.

Feather Spiral.  6"x 6" mixed-media paper with pencil and Sakura 0.1 micron black pen.
I had trouble with shadowswhen I photographed this drawing. The one corner looks
pretty light and the other dark, when they really are not. This was a fun doodle
to create, making the wavy spine and deciding how to draw the feathers.
