There are various cardboard or plastic bobbin schemes available, but the using bobbins results in folds every inch or so on the floss, and I don't like them. The plastic DMC bows are ugly and expensive.
For this methods, you need some rings or paper clips, and scissors, and a few safety pins.
Step 1: Wind off and cut
In a kitten-free location, remove bands from ONE skein at a time. Clip the number portion of the band and slip it onto your ring.
Step 2: Cut floss to lengths
You don’t have to cut the skein into lengths, but it makes it easier to take a portion of floss off without discombobulating your whole clip-full.
Don't make them too short; you'll have to rethread the needle, and it will interrupt your creative flow.
Step 3: Loop onto holder
or a paper clip. I like this shape but paper clips come in many colors and styles and you may want to color-code, or use cute ones. You want them to be rust- and tarnish-proof.
Put the uncut end of your loop through the ring or the clip, and put the ends through the loop, making a larkshead knot . Now your color number is secured with the floss, and you can use the floss without its becoming hopelessly tangled. Sometimes you can even pull a single strand off by itself, and you can put any leftover on easily.
