For quilts I make for folks I don't know as well, or who have no input, I always enclose a card telling the receiver to feel free to pass along the quilt to someone who will like and use it, if it is not to their taste. or in the case of a child's quilt, to donate it where it will get used. There is nothing sadder to me than a child's quilt in a closet somewhere, when it could be dragged around, making tents, soothing hurts, etc.
I try very hard to get input as to what folks like and don't like, and make accordingly, but none of us hits the mark every time.
