August saw my first yarn purchase in over 2 years when I needed to buy some additional yarn to finish the following sweater (which used a total of 1,834 yards of yarn):

That added 374 yards to my stash (before finishing the sweater).

I also carded and then spun some alpaca fibre into 348 yards of light fingering weight yarn, losing some of the fibre along the way (I started with 100g but ended up with 87g). There was a lot of grease in the fibre which led to some gentle felting whilst washing it out, but I’m pretty happy with the end result.
