Two Button Rag Sweater 07-Sw Knit from the neck down. You can add any patterns that you like. I did mine with a color band of color at bottom of yoke and cable on the body. It's easy to get it to fit because you can try it on as you go. It's an easy fit because you begin at the neck and work down, trying it on for fit as you go.
Diagrams help with the cables.
Large collar keeps your neck warm. Easy color design is fun to do. Can be made on a knitting machine. Add some easy lace pattern and you have vertical stripes. Patchwork Sweater 14-Sw Fun seams are the design element.
