Some of the most talented quilters are MEN. I even quilted a top for a fireman who was very talented with his selections of fabrics.
To preserve them for generations and to be able to give them eventually to your kids telling them stories about your Grandmother, I would have them framed. Maybe you could add special family pictures of her in with the frame. Do kind of like a memory box. I know your Mom will appreciate what ever you do because you did it with love in your heart !!
