Stitch Guide (see diagram):
Knit one Below (K1B): To knit one below insert the right-hand needle through the center of the stitch below the next stitch on the left-hand needle. Knit this in the usual way, drawing the loop through, then drop the stitch above off the needle.

Instructions:
With one strand of worsted-weight and one strand of baby-weight, cast on an odd number of stitches.

Foundation Row: Knit (note: this row is not repeated).

Row 2 (right side): Sl 1, * K1B, p1; rep from * to end. (editor's note: I found that knitting the last stitch instead of purling gives a nicer edge.)

Row 3: Sl 1, * p1, K1B; rep from * to last 2 sts, p1, k1.

Repeat rows 2 and 3 until desired length. Finish off.
