Once you have cast on your stitches, the next step is to join to work the body of the sweater in the round.

Before joining, be sure that all your stitches are going in the same direction and none are twisted.  The working yarn will be at the last stitch on the right needle point. If it is on the left needle point, turn your circular over and it will be on the right needle. I always line up the stitches so that the bottom lays flat on the inside of the needle as pictured at the left

Please note that you can run your finger smoothly along the bottom of all the stitches.

To Join: With the working yarn, not the cast on tail, knit the first stitch on the left needle. This is the first stitch of your rib, the beginning of your round, and the join.
