I had no idea such a thing existed until I came across it at Core Fabrics. It grabs all the scattered pins and arrays them decoratively around the perimeter. Sometimes it even grabs my small scissors.... An excellent tool to have. Apparently it is not to be used near any computerized machines because it affects the electronics. so good to know. I am keeping my IPad and the watching of sewing tutorials well away from this very useful gem, just in case. Highly recommend the Zirkel magnetic pin cushion.
