knitting afghan on circ.-wrong side!
I am new to knitting and am knitting an afghan on circular needles (which I have used before). I have had to start over twice because I am somehow knitting on the wrong side at times. I start out knitting on the right side, but them somehow I am changing to the wrong side. I am knitting back and forth, not in the round. How can I correct this problem and is there a trick to prevent it from happening again?
