Channel Island cast on This cast on method makes an attractive edging for many types of item. It is a lot easier to do than it looks. Try practicing with chunky needles, say 6mm, and some left over chunky yarn. I've opted for starting with a slip knot using the double thickness yarn but you can start with a slip knot using the single thickness yarn. I also found it is better to follow the cast on row with a few rows of knit stitch to stop the edge from "curling".
