So what is a Needle Minder? It is an embroidered patch that has a magnet inside and you secure a separate magnet on the back side of your embroidery project and you can rest your needle on top of the decorative minder so it doesn't get lost. The Mushroom Embroidery Needle minder is 1.25 inches round. It comes packaged on a card and would also make a lovely gift for your stitchy friend. Important: Please be aware that these are made with super strong magnets. The packages really want to stick together. Please keep this in mind when merchandising for your store.
