Narrowing.

Q. How do you narrow?

A. I slip one, knit one, and pass the slipped stitch over the knitted one before the seam, and knit two together after the seam, leaving one stitch on each side between the seam and the narrowing.

Q. How many times do you narrow, to form the calf?

A. Eight times.

Q. How many rounds do you leave between the narrowings?

A. I narrow every third purl stitch, which leaves five rounds between.

Q. How many rounds do you make after the last narrowing before you begin the heel?

A. Thirty-six.
