Plying

Day 277: Happy to finally have my spinning wheen back in operation after months of waiting for a silly little backordered part (the footman-to-treadle connector, a flexible plastic rod 8 mm. in diameter and approximately two inches long), I had even forgotten that I had one spindle of tan single-ply llama wool already done. I spun up an approximately equivalent amount on a second spindle, and then settled into the less-demanding job of turning two single plies into two-ply yarn.

Right now, you might be thinking, "Why not just spin a single thicker strand?" The answer is simple: strength. When spinning, the twist enters the yarn in the direction of an S or a Z depending on the spinner's preference. In plying, two strands are spun separately, each with the same twist, and then are recombined as a double-ply with the twist in the opposite direction. In other words, two S-twist single-ply strands are spun together with a Z-twist. In effect, this untwists the original strands slightly and allows a few fibers of wool to become entangled with each other, binding the strands together and making a stronger, more durable yarn in the end. I almost always ply my yarns unless I'm going for a "novelty" look. In this case, the resultant yarn is a nice sport-weight, more work, but double the fun of spinning.
