How does one draft well? I discovered that if I predraft a roving I have much better success in getting uniform thickness of the single. I did notice, however, that even though I took care to try to draft evenly, there were still lots of spots that I had to re-draft while spinning. I even held the fiber in the air as I drafted to take advantage of light coming from behind to see areas that were less well drafted and tried to draft out those areas. What are you looking for when you pre-draft roving well?
