These are very unusual items to find. Two sets of darners. The first is the Perfect Darner. It is a set of two footed oval ring hoops. They can be used for a variety of purposes, mostly to fix holes in socks, clothing, and tablecloths. It works by tightly securing the item inside out on a raised hoop so it is easy to repair on a sewing machine. Zig zag stitches bind the tear together on their edges so the repair is almost invisible on the other side. The Easy Darner works with a lower profile two piece hoop for small repairs with springs to load on the sewing machine needle. Comes with full instructions for both sets and original boxes. Boxes have some wear.
