I made a quilt for my sister's baby boy-- a 10"square quilt because he was all of 7" long. I used my very favorite cotton shirt for the purpose.
My sister and her husband were quite touched by the loving keepsake , said it meant so much to wrap him in it and hold him for two hours. The nurses asked if they could take a picture of the quilt to show the staff as an example of how to honor a short life in the hospital. My sister agreed. She has kept the quilt in her keepsake box of David's things for the past 20 years.
