Needle minders are awesome at looking after that pesky needle and ensure you have no minor accidents when stitching up a storm. MATERIALS: Each needle minder is made from offcuts of birch plywood which means less waste going into landfills. Hurrah! The magnets are neodymium; although they may be small, they are VERY strong. Keep away from little hands, pets, and electronics (this includes sensitive medical devices such as pacemakers). Due to their size, they also present as a choking hazard and are best kept away from children. Each needle minder is sent on a recycled backing card with instructions on the reverse.
