Direction Matters! (to most people)
When ordering your SkeinTwister, you can choose to have the hook rotating in the CW or CCW directions. You may not think you have a preference, but you probably do!
Check out the photo, and choose the direction that corresponds to the way your skeins currently look.
You can change the direction of the SkeinTwister once you have it, but it requires unscrewing the base and unscrewing and swapping 2 wires. All it takes to do this is a screwdriver or two, but it's better to just order it in the direction you want!
