The little sweeties I made above are called Rolags. Here is a little video by the über-talented Michelle Snowdon over at Wooldancer that shows you how to make them + how they can be spun on a wheel to make yarn...
Tip for other Fiberistas making rolags this way :: I'm finding it's a bit easier to roll the fiber off the drum carder when sandwiched between two dowel rods so it doesn't slip.
Check out some of my batts (and rolags very soon) here.
