For the first time ever my spouse has said he would wear a knitted item other than a scarf! (He's always been too warm with a sweater before) I'm so excited! The vest pattern he and I have chosen calls for making an "edge stitch" at either end. I've looked at the appreviations - no explanations. ALSO - the pattern calls for working the wrong side rows "as seen". Can I assume that means that if it looks like a knit stitch I knit it, and if it looks like a purl stitch, with the bump, that I purl it? I've been knitting a long time and never seen this language before. Help!
