I bought three of these quilting magnetic needle holders to give as presents to friends who do a lot of quilting. However after trying one out decided to keep one for myself to stop stabbing the arm of my settee. When I gave one to my friend she put it on the jumper she was wearing which I thought was also a very good way of using the needle holder. The magnet is strong enough to use on a quilt sandwich, three layers of material. A great little magnet keeping needles safe.
