Like many yarn crafters, I’ve got roughly a thousand and one works-in-progress laying about, so I regularly find myself in need of more project bags. As I knit and crochet over the years, I realized that the best project bag is nothing more than a simple rectangle with a drawstring top. You can toss the bags in your purse to keep your skeins in order, you can toss them in a suitcase, and you can easily store them with your other WIPs without worrying about yarn running amok.
