This isn’t just any Dot — our Needle Nanny incorporates two very strong Rare Earth magnets that promise to make it one of the most versatile and indispensable tools in your sewing kit. The magnetic back is removable, which allows it to be worn as a pin, and the powerful (and pretty!) magnetic surface acts as a needle minder to keep your needles and scissors firmly in place while you work. Even non-quilters can appreciate this clever accessory: Wear it as a magnetic pin to add a little extra flair to hats, coats, shirts, and scarves! Needle Nannies are 1-inch in diameter.  They are not waterproof and should never have prolonged exposure to liquids. Due to the powerful magnets, NEEDLE NANNIES SHOULD NOT BE WORN NEAR A PACEMAKER.
