Hi. I'm trying to knit a hat (my 3rd project so please excuse any incorrect terminology). I previously knit 2 scarves, and this is my first time knitting with circulars. Unfortunately, I messed up the joining. I cast on 110 stitches. Then I put on a stitch marker and knit a row. However, when I neared the stitch marker, some how (I might have slipped?) I missed the stitch and now am down to 108 rows. There's is now about an inch and a half worth of yarn connecting the right needle to the left. Where did I go wrong? And can I fix it? Its still early so I could always start over, but I would like to learn how to solve this problem in case it comes up again. Thanks for any help!
