You may be reminded of the book Charlie and the Chocolate Factory when knitting one of these little bags, which start with a simple bias square. As stitches are picked up from the four sides, a round-bottomed bag emerges, perfect for carrying a supported spindle or two, a little wooden bowl, and a bit of roving yet to be spun. Sarah Swett enjoys the “pure, rhythmic pleasure” and whirling sound made by a supported spindle turning in the bottom of a wooden bowl in her lap.
