make a slip knot on a needle and hold that in your left hand.
knit into the knot, but don't slip the old stitch off the left needle.
You'll have a stitch on the left needle and a new one on the right needle.
slip the one on the right needle onto the left needle.
knit into that stitch, again, not slipping it off the needle.
transfer the new stitch onto the left needle.
keep going until you have the right number of stitches on the left needle.


Here are the steps I copied and pasted from one reference.
