Estelle's Beechwood Darning Mushroom is the perfect tool for mending sweaters, blankets, and other large items where you need a bit more space to do your repairs. The top comes off to make it easier to store, or for mending on the go! To use a darning mushroom, place it inside the item you wish to repair, and stretch the item gently around it. You may find it helpful to use an elastic band to keep the item in place while you work on your repairs.
