This method is for K1, P1 and slip stitch ribbing
Thread the tapestry needle from right to left through the edge stitch (and if the next one is a knit stitch, through the knit stitch too.) Drop the worked stitches off the needle.
1. Beginning with the purl stitch, thread needle from left to right through first stitch on the needle and pull firmly. It is important that the yarn does not leave a loop showing on the right side of the fabric at this step. * Leave the stitch on the left needle.
2a. Thread the yarn from right to left through the first knit stitch, the one dropped off the needle and
2b. the second stitch on the needle (a knit stitch) and pull firmly. Leave the stitches on the left needle.
3. Thread the yarn from right to left through the first purl stitch on the needle, pull firmly and slip the two worked stitches (one purl and one knit stitch) off the needle. The knit stitch will appear half finished; it will be completed in the next repeat
4. * The fiddly part of this cast off is in the tension of the yarn as it is threaded through the stitches. If the yarn is too loose where noted in step 1, the next stitch will not sit correctly even if properly threaded through the next stitch.
Make sure the yarn is pulled taut (but not too tight.) You may need to play around a bit to get the stitches to sit neatly, but once you’ve got it, the beautiful finished edge it creates will make you glad you persisted!

Yarn published earlier this year.

Once you master this technique you would not use anything else for casting off single rib because the finish is very good. I also use invisible cast on for single rib – it really gives a professional look to a garment. The cast-on is one of several in Creative Knitting, a British publication several years ago.
