While at the Fleece & Fibre Show in New Zealand, Joanne demonstrated how to take fiber off of the large drum of a carder as a roving rather than as a batt. Otto captured it in two short videos that we think you might enjoy. If you like, you can view them at our Flickr site. Or you can watch them right here! (The wonders of modern technology :-)
Isn't that cool? The diz that Joanne is using is a large button. She keeps it pretty close to the card cloth, and is careful not to try to pull too much through at once. You also have to keep in mind the length of the fiber itself. It's a lot like drafting when you're spinning.
If you give this a try at home let us know how you like it. We'd love to see some photos of your drum carder roving too!
