So sorry for your loss. My sons’ cousins asked me to make a quilt for their mother after their father passed. They sent me 18 cotton shirts. I sent them some pattern ideas and they picked something very simple. I made 4”x8” blocks and placed them like setting bricks or tiles - offset. For the back I used the backs of the shirts - large pieces done the same way. It was easy for them to pick out a shirt and say “I remember him wearing this at ...”. Simple to do and very well received.
