I’ll try to explain what happened the best I can. I did the 2 x 2 ribbing for the first 5 rows as indicated by the pattern. From there on I simply did knit stitch since I was working in the round. This would give me stockinette stitch on the “outside” of my work.
When I switched to the contrasting color I ended up with what looked like a garter ridge with the contrasting color going through the middle of the ridge on the stockinette side. Because of this I ended up turning it inside out so that ridge was not visible. I’m not sure where I messed up. Does that make sense? Here is a picture of what happened:
Instead of it being a seamless transition that’s what I got.
