I finally opened the ball winder and yarn swift that I bought in December, and wound a hank of pretty blue cotton that I got in the yarn swap. That went well, and I now have a lovely center-pull ball to show for it.
I then tried to wind one of my many skeins of ArtYarns Supermerino, and that did not go so well. The bottom of the ball kept falling off, so I tried to rewind the skein, and now it’s hopelessly tangled. While suffering, though, I did have the presence of mind to separate the skein into two sections, so that if I use it to make booties, I can do them in the two-at-a-time method, which I am now officially rocking at.
