Help---rejoin yarn

How-to Questions
1

I am knitting these baby booties and I am confused on how to rejoin the yarn. I found a video on here on how to do it if there is a tail of yarn, but I don’t have one. I have made it down to the point where I am to rejoin the yarn, but I don’t know how. Here are the instructions:

Row 20: Knit 9, beginning with next 2 stitches bind off 21 stitches, knit across remaining 9 stitches. (This includes 1 stitch already on right needle after the bind-off.)

Put first set of 9 stitches on holder.

Rows 21-23: Knit 9 stitches on needle.

Bind off all 9 stitches; cut yarn.

[B]Rejoin yarn where you started binding off 21 stitches.[/B] Cast on 12 stitches using cable cast-on method.

I think I would pick up a stitch at that spot by pulling a loop through and then turn and use both the tail and the yarn to knit into that first stitch to secure it. I’d count that as my first cast-on stitch.

This is a different one, all right.:think:

ETA: Come to think of it, you could use the last stitch of the 9 and pull your yarn through there. I’d still use the tail and yarn for the first stitch, or make a point to weave in that end very securely.
