How to Join Knitting in the Round
I know why you are here. You most likely just started knitting in the round on circular or double pointed needles and the pattern you are using states "join yarn" and begin knitting in the round.
The reason you will be joining the knitting is so that you can knit in one continuous, seamless loop.
Joining your knitting is REALLY easy. I'm going to show you how it's done.
How to Join in the Round Knitting: 4 Easy Steps
Place a stitch marker on the end of the needle that has the first stitch you created.
Bring that end of the circular needle around to meet the other end of the needle.
Make sure there are no twists in the stitches on the needle. The bottom of the cast-on stitches all pointing toward the middle of the circle created by the needles. Your needle with the working yarn will be in your right hand.
Go ahead and work that first stitch on Round 1. Joining complete! That’s all there is to it.
