Pair of magnetic sewing guides, you can join them together for a bigger guide, use one on each side to guide fabrics with a small width, or use only one. The pads are for a neodymium magnet with a maximum thickness of 1,5mm. Use superglue (cyanoacrylate) to glue the magnets. You can upcycle some good magnets from old earbuds.
