Your quilt is lovely. I love that you are making it in memory of your mom! I hope you continue to post your blocks as you proceed. You have given me an idea that might help me... as I lost my dad recently. It might help me if I can create another project in commemoration of him. I already made him a 'Thank you for your Service' quilt for his 90th birthday. Maybe it will help if I start another quilt in his memory.
Love your quilt and the memorial to your Mom, thank you for the idea!
