I love your quilt, pattern and fabrics. I've been going to make this pattern and just moved it up on my list for a donation quilt. And I've debated about using gray but hesitated. Now I know I will.
I wish I could quilt as nicely as you do. I have to pay to get mine done. Except my local quilt shop donates the quilting and batting on the valor quilts. A huge gesture in my opinion.
