I attempted, and completed two memory quilts for a dear friend of mine whose mother past away last year. I made one for him and one for his sister. I didn't really expect what I had gotten myself into, just excited for my first two commissioned pieces. (And to be able to make family heirlooms for them.)
Design has to be simple, additional fabrics necessary to hold everything together including the bathing suits he included in his clothes bag. It was a lot of work to try and stabilize everything but still had some bunching and issues... It turned out relatively well. And they loved the finished pieces. Said they never thought they'd have something like this to pass down to their kids. It was a very exciting moment giving the quilts to them. I'd do it again... Even though I said I wouldn't. Ha!
