Without turning the needle, place the needle in your left hand. The yarn is coming from the far left stitch. Pulling the yarn so that it is snug, knit the 3 stitches from the left to the right needle. Everything is normal EXCEPT the yarn is coming from the last stitch in the row instead of the first when you begin knitting this row.
When you have knit all 3 stitches onto the right needle, slide the stitches from one end of the double-pointed needle to the other. Repeat these steps, pulling the yarn snug at the beginning of each row to insure even stitches. Bind off normally.
