Double rib (2x2 OR K2-P2)

This fabric alternates 2 knit-stitches with 2 purl-stitches lengthwise. The working method is essentially the same as for single rib (1x1, or k1-p1, see Single rib (1x1 OR K1-P1)), and it’s convenient to cast on in pattern.

	With a crochet hook and waste yarn, chain the required number of stitches. Change to the main yarn, then insert a knitting needle into the back of the chain stitch, yarn over, and pull up a loop.
	At intervals of 2 (work into 2 chains, skip 2 chains), pick up and knit across (see single rib).
	Place a marker as for single rib; work 3 rows in stockinette stitch. Row 4 (wrong-side facing), insert the needle as shown by the arrow and purl the stitch and the pulled-up loop together.
	Purl the second stitch. For the third stitch, insert the needle into the main yarn purl bump from Row 1 and knit it.
	Work the next (fourth) stitch in the same manner.
	Return to the stitches on the needle. Purl 2 stitches from the needle, inserting the needle as shown by the arrows, then knit 2 stitches from Row 1. Repeat across.
	Purl the last 2 stitches, as shown by the arrows.

	Step 7, as seen from the right side; the double-rib cast-on is complete and counts as 2 rows. Follow the symbol chart to work double rib.
