When I first started spinning, some fifty years ago, I thought that plying was simply a waste of time. I thought that if you wanted a thicker yarn, you should just spin the single thicker. It took me a bit of work and a really good teacher to show me just how wrong I was! Plying gives yarn amazing stability that it simply can’t have as a single. Its structure allows for many beautiful blends of fibers and colors. Plying can also create an unending variety of textured yarns such as bouclé’s and cables. Plies are, of course, always strong.
