I used a 'lap size' quilt for my mom's casket. It was folded in half and draped over the bottom half of the casket. Then when we went to the graveside service it was draping the entire casket. She had fallen in love with this quilt and it was the last one I made before her passing.
the quilt was a simple five fabric quilt of yellows and bluess and white and sparkled in the sunlight. It really brightened my mood.
