Wow, great blind string. And the tangles you used are just amazing. I love the weavy seeds in the middle. Very much movement and organic feeling or touch in your tile.
Delightful! Love your shadows.
I must say that your patterning is wonderful, however, your shading is what makes the patterns sing!
I agree whole heartily with the comments about the shading. Like the shadows of your dancing seeds.
A great tile with outstanding shading.
Very bold and beautiful!
