How to Join in the Round Invisibly To join in the round invisibly, cast on one more stitch than your pattern calls for. Then, when you’re ready to join in the round, slip this extra stitch to the left needle. Using the working yarn and the yarn tail held together, knit the first two stitches together. Now drop the tail and knit as you normally would.
My favorite stitch, Linen Stitch: Works on an even number of stitches. Row 1: *Knit 1, slip 1 with yarn in front. Repeat from * across, ending with a knit 1. Row 2: *Purl 1, slip 1 with yarn in back. Repeat from * across, ending with a purl 1. Repeat these two rows for pattern.
