Joining yarn

Hi. I’m sort of new to knitting-when knitting in the round, like making a hat, how do you join the yarn after casting on? Jenna :shrug:

The first CO stitch will be on the needle in your left hand, the last one where the yarn is attached to the skein, is in your right hand. Scooch the stitches to the tips and start working the first round. Make sure you pull the first couple stitches tight so you won’t have any gaps. It helps to put a stitch marker on the needle before you knit the first stitch so you can tell where the beginning of the round is.
