So wonderful what you are planning to do for mom, just a thought as to working this up for her; are your siblings able to help with any of the hand work? Even just a bit that they could also put their signature on? My thought on this is years ago, I started a applique maple leaf quilt, cut out all the blocks and leaves, and then came KIDS - my grandmother knew I wouldn't have time to complete it, so she took all the parts and pieces, passed them among many family members, and each worked on a block and signed it. Great Grandma Rose was the last to work on it and did all the hand quilting. What a treasure my family worked up for me and my kids. Just a thought!
