I have that exact issue with my family , everything I give them ends up be saved, even potholders. This year I made them give me a potholder ( I had made) with some ... food, gravy, anything to show they had used them. It was a condition for them getting the quilts I had made them( they did not know what they were getting) . I told them all if they did not use them, they could donate them , but if they kept them ... I would come to their house and spill something on it myself if I found them in a closest! They finally got the message.
