Joining on circular needles

I’m trying to learn knitting on circular needles and came across a slight hindrance in my progress: the join! I looked up the tutorial on this website but it did not really specify how I’m supposed to join the two ends of the circle together. The pattern I’m using is for a hat. I cast on 80 stitches and the first 10 rows are a k2p2 rib pattern, so I joined the sides and knitted the first row of the rib pattern, but when I came to the end of the round I had an uneven number of stitches! I’m supposed to end on 2 purls, but I ended up with an extra knit stitch. Is the join supposed to be counted as the first stitch, meaning my join-stitch is the first of 2 knit stitches? Or do I join first (meaning 1 knit stitch, from the looks of it) and then start counting?

HI, welcome to KH.

Your first knit stitch to join your stitches into a circle counts as your first knit stitch. It will be the first knit of the k2. HTH

You probably forgot a stitch somewhere and did k2 p1 or something. So look back at the start of the round and make sure you have 2ks, then 2ps, and so on. Or did you k1, then start the k2, p2? You may have CO 1 stitch too many too. To join, that’s all you do -work the first round of the pattern.

When I join mine I take the 1st cast on stitch and slip it onto the other needle and then take the last cast on stitch and slip it over the stitch I just put on that needle and then put it onto the other needle. If you have the correct number of Co stitches you boobooed somewhere…we have all been there. All you have to do it check them and frog them out to that stitch. Sorry, hope this helps some…
