Darning is a traditional European needlework that repairs holes and worn areas of clothing. For repairing holes, stains, and fabric sagging. Mushroom-shaped darning mushrooms (sold separately) can be used to easily fix socks and clothing. We offer 24 colors of wool-like threads that can be arranged not only for darning but also for crafts. Two types are available: a blue box with a mature nuanced color and a red box with a pop and energetic color.
