It's absolutely BEAUTIFUL !! What a wonderful gift, what a wonderful way to wrap up in grandma's love....... a keepsake for the ages.
My own mother passed while my children were young. I saved baby quilts she made to give to their children when the time comes. It makes me smile to know they will have a piece of their great grandma's love even though she never got to see them face to face.
Awesome job in finishing your mom's work.
