Don't know what kind of roving I am using, just a $6 bag I picked up at the LYS. Hey, I found my biggest problem, though. I ran across a website that said if you are right handed to hold the spindle in your right hand and draft with your left. I realized I was mirroring the Knitty Gritty video and holding the spindle in my left hand. It is actually a lot easier since I switched hands this morning.
I may just get the hang of this!
