I'm designing my next set of yarns... Thick 'n Thin. I started by sampling with a roving I dyed. This New Zealand wool roving was dyed using the casserole method... Yes, another experiment.
I spun a thick and thin single of this roving, keeping track of how far apart I was making the slubs and also how long each slub was. If the slub is longer than the staple length it can pull apart easily. The distance between the slubs is a matter of taste. I plied it with a single of "Jasmine", English Angora...thinking that it might create a soft halo. Well, that didn't really happen.
I knit a sample swatch, using size 8 needles. I didn't want the thin parts to be too loose
or the thick parts too tight.
The new yarns should hit the Esty shop in a few days.
