Making Ribbing Look Seamless

To make separate piece ribbing seams look like they were knitted in the round, make sure you knit your ribbing this way.
•For K1, P1 ribbing, use an even number of stitches. On wrong side rows, P1, K1 to the last 2 stitches and end with P2. On the right side rows, start with K2 and then repeat the P1, K1 ribbing to the end of the row.
•For K2, P2 ribbing, use a multiple of 4 stitches plus 2 stitches (i.e., 42 stitches). Knit the wrong side rows using P1 to start, then repeat the K2, P2 ribbing to the last stitch and end with a P1. The right side rows start with K1 and then repeat the P2, K2 ribbing to the last stitch which will be a K1.

When sewn together, the seam will be invisible.
