My mother is a jigsaw puzzle addict, she buys new and used puzzles the ones she completes she podges them and frames them and gives to family and friends as gifts, unfortunately some of the used ones she buys are missing one or two pieces, she will complete them until the bitter end hoping the missing piece mysteriously pops up. but I know it kills her to throw them out! Is there any craft we can make with them? any suggestions! please help.
