If you are adding embroidery floss, ribbon, fibers, etc. to buttons eyelets, or other hard to thread items, try this. I use plastic loops for dental floss. You can purchase them anywhere in with the dental floss, toothbrushes, etc. They come in packs of 10 or 12 and last forever. Put your fibers through the loop, thread the end through the button hole and pull it through. Voila, its that easy. It will save a lot of frustration.
