This DMC bobbin winder is a compact tool that helps you wind embroidery floss, ribbon, or thread neatly onto bobbins for cleaner storage. It includes 1 plastic winder and is made for stitchers who want faster, more even wraps on both cardboard and plastic bobbins without hand cranking every turn. Wind at a steady pace and stop before the bobbin is overfull so the wraps stay smooth, the ends tuck in, and the bobbin fits its case.
