Ok, I know an elderly lady. Her husband had made this item about 25 years ago. It is basically a large heart with heart hole cut into it. Then a board across the top has 4 fishing lines with silk (Christmas Ornaments Like Balls) balls hanging down. behind the silk balls are wires that stretch across the hole in the middle. When you open and close the door the balls bounce on the wires making musical sounds until they stop. I would love to get a pattern of this, but don't know what it is called to even begin looking. Any suggestions?
