On an even number of stitches. The best results are obtained when your tension is loose.
Row 1: Cast on the stitches very loosely for ease. *Slip the needle behind the 1st stitch and insert the needle into the 2nd stitch to knit it knitwise. Do not let it fall off the needle. Then knit the one you slipped, knitwise *. Repeat from * to * until the end of the row.
Row 2: Knit the 1st stitch of the row purlwise normally. *Skip the next stitch to purl the 2nd without letting it fall off the needle. Purl the first stitch purlwise*. Repeat from * to * until the end of the row. Repeat these two rows until you have obtained the desired length.
