These are Hooks that used to be Pattern Hooks. You can purchase them new from places like Wawak. The cords eventually fail but I save the Hook. They are still solid and great for creative projects! I've had two designs that will utilize them and have been saving them just for those designs.
They are free (2 per person limit please).
If you want to make the Laundry Basket, you can find the sewing pattern HERE.
