Have you ever taken out your favorite color thread and found that it has become unraveled and is a mass of awful tangles? Delicate sewing and embroidery threads can easily unravel or lose tension when not in use, and especially if they somehow roll on the sewing table or storage shelf. Peels thread organizers are small bands of flexible memory silicone that grip firmly around most sized spools to keep thread tails protected from unraveling.
