My favorite new...tool is a Woolee Winder. I was even able to buy some extra bobbins so I'll be less likely to find myself in a bobbin bind!
The bobbins are smaller than my standard Kromski bobbins, but because it winds so much more efficiently than I do when I have control over moving the singles on the flyer, it still holds the same amount of fiber/singles on a bobbin.
The photo shows 4 oz. of singles, hand-dyed BFL from Fiber Fancy. (Love her fibers!!) I have another 4 oz. to spin, the plan to do a 2-ply yarn. I have no idea what I'll do with the yarn, but that's not really the point, is it?
