I snuck in a super quick spin after the holidays. I had some unknown fiber in my donated stash bucket. The only thing I know is that it’s from the Weavers Loft, the fiber is brown and I had 2.9 ounces. So I got it on the wheel!
This was quite literally the dirtest fiber I have ever spun. My fingers turned BLACK where the fiber was passing through my fingers. The prepped fiber must have not been washed a ton after shearing. Which is fine but a new experience for me!
I ended up spinning all the fiber on one bobbin and then caking it up into a center pull ball to ply back on itself. When I was done I had a 2-ply skein that measured 114 yards over 74 grams. So a worsted skein with a few thicker spots.
I had to wash and wash and wash this skein to get all the grime out. But I got there and the skein turned out really pretty. Now to plot my next spin! Happy Spinning!!

All your work tuned out some lovely yarn.
Do you have to wash the bobbin after spinning a dirty fleece?
In this case I did not
I hope your wheel is still clean. It sounds like it would be hard to get the gunk out after a spin like that.
The gunk mostly stayed in the fiber and my fingers
