Help! Knitting in the round!

[lucymaude90]

I have been trying to knit a gaptastic cowl for almost 4 months now, i had so many problems at first that i gave up! I bought some new fantastic yarn ( not from wal mart) and flew through quite a bit of it last night. I picked it up this afternoon and have managed a huge boo-boo i need help! I was thinking of just ripping out a row and starting from there but i have no idea how to do that 1) in the round and 2) with a K1 P1 pattern.
