Your quilt is lovely and will be "So Loved" I am 11 years out now from Breast Cancer myself those hugs and prayers mean alot. I wish I had a quilt when I was going thru it all. In fact that is when I started quilting. I wanted to add something beautiful and new to my life : )
As for my thoughts..I love borders I think it frames the quilt. Any colors would be great! Wonderful job!
