I'm completely devoted to spinning fine, smooth wool for backstrap weaving on Peruvian spindles these days. I spent the whole of July spinning a glorious green Targhee gradation from Yarn Hollow, and now I've moved on to the orange gradation (Cream Tangerine, to be precise), and some indigo blue I dyed at a recent workshop.
There's just something immensely satisfying about spinning for a purpose, knowing how the yarn needs to be, and consistently getting better at it.
