I agree with the suggestion to wait and glad you see the benefit in doing it. While working on other things, you can do some planning - are your father's sweaters wool? if so, they can be wet felted. You can google that to learn what it is. Felted wool makes great tote bags, etc., in case you want to do something other than a quilt for some of the family. If the sweaters are not 100% wool, they won't felt, so back to the quilt idea.
