Playing with fluff
It’s an obsession that matches my earlier experiences with beadworking. I have collected all sorts of fibers to play with: cat fur, recycled silk fiber, wools, alpaca, bunny down, dog down, and assorted stray fibers from deconstructing garments and weaving thrums. I made spindles, bought large dog slicker brushes to use as budget hand cards, got Dad to drill holes in scrap 2-by lumber for spindle stands and makeshift lazy kate. When the egg dyes went on clearance, I bought some of those and some fiber reactive dyes, and collected lichens, onion skins, and oak galls. Then came the umbrella swift and ball winder, building a frame loom, making weaving shuttles with Mom and experimenting with heddle options. And I’m still knitting and crocheting, sewing and embroidering, and possibly tatting. Maybe this is worse than the bead thing. 
I started spinning by rolling cat fur down my thigh, the most primitive form of making yarn. Then I learned spindle spinning by parking and drafting for what felt like forever, but it didn’t take too long to learn to draft and spin. Keeping tension on the singles while plying is kinda hard, especially when plying directly from one spindle to the other. At least, I’ve had trouble; the single has drifted apart a few times while I plied the sock yarn. It’s easier to use my spindle stands to provide tension while plying, but plying spindle to spindle is really portable. Better yet is ply-on-the-fly, where the single is spun and immediately chain plied. I think that’s my favorite spinning technique!
My second favorite technique is actually making rolags, which is a type of fiber preparation for spinning. I card out the fiber and roll it up off the hand cards, making nice fluffy tubes that are really easy to draft. They make for a lofty yarn, too. And I can card in whatever grabs my fancy, like alpaca with bunny fur or wool with recycled silk. Really, I can see where making my own blends could get out of hand.
My least favorite fiber task so far is washing and picking fleece. Alpaca fleece is considered to be easier than sheep fleece to process but if this is easy, I don’t want to try hard. A fleece is heavy and dirty and sort of matted together. It doesn’t help that I don’t have a good place to wash it, even though an alpaca fleece doesn’t have to be washed the way a sheep fleece would to be clean.
