Unknowingly, I must have been quite afraid of plying my yarn. After spinning both of my first lots of fibre, I took ages to actually sit down and learn about plying. It took a while to find a suitable tutorial too. In the end, I came across this one which was incredibly helpful:
I learned how to wind an Andean bracelet and what it is good for. I quickly had a two-stranded ball of yarn that I could then easily ply. I really enjoyed it and am looking forward to washing the yarn soon to see how it will set. I am quite proud of it, tiny little hank of hand-spun that it is.
