Do you? I'm rather new at knitting, but I wouldn't dream of it. I did my first pair of slippers recently and I didn't have the right size circular, so I made size 11 dpn's out of dowels like Amy's video says, and I did them, it worked, but the next pair I did on circular, and comparatively it was a breeze!
I just started a vest that's on single point 6's and I'm wishing I had my set of Denise's circulars that I ordered already. I hate knitting with the long sticks! I'd prefer something on DPN's than long sticks. I guess I hold my right elbow out too much, and it gets tired.
For what it's worth, that's a green knitter's opinion!
