This is one of my favorite reversible items made in double knitting technique. Double knitting is a technique that simultaneously forms two layers of knitted fabric while you knit with just two straight needles. It makes the items reversible and another benefit from double knitting – it prevents the fabric from curling in. I found out that it much quicker and easier than using circular needles and it requires less yardage of yarn. The advantage of learning a double stitch – it could be used as an element in many items (hats, cowls, double layered scarves, sleeve and mitten cuffs, bags, pillow cases, phone cases etc).With no seams at the side on a straight item or with no seams at all to be made.
