If you don't want to be rude (even though you have every right to say whatever you are thinking!!!) just tell them you will make them a much larger quilt. Tell them you have put it on your list and will get to it eventually! That way you have been polite, but are blowing off those incredibly rude people.......But, for the future, a lot of folks have no idea how to care for a quilt and will need to frequently wash a baby quilt. It would be a good idea to attach a small note with laundering suggestions.
