Lab Robe 36 inches by 48 inches is about the Right Size... make of pretty fabric, because in most Senior Living places if Family doesn't do the laundry it goes and gets mixed in with all the rest. In HOT WATER and HOT Dryers.. Plus make sure you sew a name tag on or embroider her name or use a Sharpie to write her name on the Quilt... I used to work in a Nursing Home and make sure you take a pictures of the Quilt and send a photo to the Daughter and ask her to make sure the Lap Quilt is added to her official list of Belongings.. Have the Daughter take a photo of the Lap Quilt with the lady so they have PROOF that its hers as well as Proof that she has it... because Nice Things seem to Walk off in the Nursing Homes/Senior Homes... What a Loving Gift for her...
