This listing is for one Bombyx silk cap, buy as many as you would like. These are fun to spin, each cap weighs about 0.4 to 0.5 oz.. There are several methods of spinning from a silk cap. Some like to put their hands in the center and push out and draw the fiber out thinner and thinner and then spin from that. I like to pinch off a bit off the surface of the cap and spin from that. These caps take dyes very well, I have the dye needed listed in my store also. I have more fibers listed in my etsy store.
