My favorites for quick and easy are the traditional 9 patch and rail fence. Another that is fun is stack and slash (do not confuse with stack and whack). Be aware that nursing home laundry is hard on anything laundered there--or it can totally disappear! When my husband was in a care facility, I was there often enough that I requested they not launder his quilt and I brought it home for that. It depends on how often you or another member of the family visit Auntie if that will work for you, too. Be sure the quilt has her name on it and in such a way that it can't be removed.
