I made a jumper a few years ago and was left with less than a ball (75g) of the yarn. I wanted to use it up now.
The yarn is Novita’s Puro Batik, a 100% acrylic which feels and looks a lot like cotton. I thought the best way to use it up was a cowl. It’s just a straight tube in seed stitch and I carried on knitting till I ran out of yarn. Easy peasy, and quick. I love the look and feel of seed stitch, and I quite like knitting it, too. One less odd ball of yarn in my stash! Hurrah!
