Recently, after seeing a beautiful example of corrugated ribbing, I couldn't wait to try it myself. From my stash I pulled out some Shetland spindrift in a moss green heather and a pale yellow and got started on a swatch. I felt impaired in some basic neurological way! The idea is quite simple, it's surprising that the doing of it is not, at least for me. I found I had trouble with tension, yes, but also with the placement of the yarn to carry over. I'm still not quite comfortable enough to start a project.
