I had knit one sock with k2, p2 ribbing and one with k1, p1 ribbing. I also knit one sock 5 rounds longer than the other. Oops.
I decided to perform a little sock surgery. I grabbed my 6 year old to snap a photo as I snipped a stitch just under the ribbing of the shorter sock.

I removed the ribbing and put the live stitches back on the needle.

I knit 5 more rounds and some k2, p2 ribbing then bound off using the sewn bind off.

Presto! Matching socks!
