Corrugated Rib Stitch

Corrugated ribbing is a beautiful two-color ribbing pattern that is perfect for colorwork projects like hats and mittens. In this video, Corrina Ferguson demonstrates how to work a corrugated ribbing pattern in a 2×2 (knit 2 stitches, purl 2 stitches) pattern.

This technique can be used for any ribbing pattern. When looking at the work from the Right Side, the knit stitches will be in one color and the purl stitches in the other color. As long as you follow that rule, corrugated ribbing can be worked in a variety of simple ribbed stitch patterns.

2×2 CORRUGATED RIBBING

Corrina works the 2×2 corrugated ribbing on a swatch worked back and forth in rows. The ribbing pattern is worked over a multiple of 4 plus 2 stitches. Corrina knits the rows as follows:

• Right Side: *Knit 2 stitches with Color A, bring Color B forward, purl 2 stitches with Color B, move color B back; repeat from * to the last 2 stitches, knit 2 stitches with color A.
• Wrong Side: *Purl 2 stitches with Color A, bring Color B to back, knit 2 stitches with Color B, move color B forward; repeat from * to last 2 stitches, purl 2 stitches with Color A.

It’s critical that the yarn is moved properly so that all the floats stay to the Wrong Side of the work. Corrina shows the Wrong Side of the work, noting how the stitches are covered by the yarn floats.
