Yeah thats true actually. I have 2 circs, & 2 sets of DPN plus 3 other sets of straight needles. I use booby pins are stitch holders but you have to be careful as its easiy to drop sitches if your not watching.

I like to do the legs on the circs over the DPN as I worry about the gap between sitches/needles with the DPN.

I can't remember what length my circs are. 30 I think....
