The first week, after figuring out exactly what the parts of my wheel were and all that, we started out with some silk hankies and Corriedale.
Once I got home, I just grabbed some of the random fluffs of fiber that I had gathered over the years. Roving samples and things like that, anything that wasn't a complete and labeled braid that could be a project in and of itself later. And with those, I added to my bobbin's collection:
I filled up an entire bobbin very early into the class, and now my second is also basically full.
And check out Woolen Diversions for more spinning inspiration, she's done some great stuff!
