This darling (and very useful!) wooden darning mushroom includes two top sizes, providing medium and large surface areas for darning. Darning Mushrooms are perfect for repairing sweaters, blankets, socks, and more! This is a wonderful way to extend the life of your clothing. Choose the right size for your repair, stretch your worn knit over the top of the darning mushroom, and secure it in place with an elastic band or hair tie around the groove to easily repair your project. The tops can be interchanged on the screw-on handle. Topper (disc) sizes are small (2.36 x 5.9 inches) and large (3.15 x 5.9 inches). Happy mending!
