My wonderful friend Sheila bought me the notes from the Pacifically Passap Seminar. There was a pattern for the carpet stitch hat and I tried it today. It is sort of cute but I would not wear it. This is 224 yarn. You can probably make this hat in less than an hour once you see how it is constructed. My loops are not large and that is because I decreased the tension more than the pattern stated. I would also make the rib a little tighter than the pattern called for .
