This is a 4.5 oz crazy ball from Spinner's Hill. It is now 2 bobbins of singles for a heavy worsted to bulky yarn.
This is BFL from River Poet, colorway Event Horizon. This is some of my oldest fiber stash. It is now 2 bobbins of singles to become a worsted weight yarn.
This is BFL Swirl from Gale's Art in the Moldy Pumpkin Colorway. In a moment of insanity, I decided to spin this as fine as possible. I have almost 2 oz of singles, and 2 more ounces to go.
