I am doing my first knitting in the round project (the little i-cord baby hat in the first Stitch and Bitch). Once I sat down to start I realized that I didn't have the right sized circular needles. The pattern tells you to start on circular needles for the first 5 inches and then switch to double pointed needles. So anyway, though I have never knit in the round before OR used DPNs before, I wanted to start the hat, so decided to do the whole thing on DPNs and I've knit the first couple of inches. That should be okay, right? Will it make any difference in the outcome?
