I made one t shirt quilt for a charity organization to hang in their waiting room. It was t shirts of events they had sponsored in the past. It came out wonderful and they loved it but, I swore never again.
The truth is I hated making it. It is not like regular quilt fabric and very heavy on my old wrists to quilt it with my domestic machine. I know the family loved the sweet deceased lady and want a memento. I would refer them to the site too. But, I hope you know, it is not like quilting with regular fabric and can get heavy to wrestle with.
