This stuff has the most amazing color. Unfortunately, like with the peach, it's all in the sericin, which means that the silk would degum to be white when finished. There are some applications where the silk is left raw, and there are ways to degum by fermentation that leave the color intact; I'm investigating how to make it work.
This is what happens when the sun hits it. The side of the itomaki makes such a solid reflective surface that I was able to cast a little beam of light onto the side of the house.
The reel with the cocoons again. The cocoons almost wash out on the sun-side, because they reflect the light so much. This was not taken in a weird patch of shade; it's under dappled light from an overhanging tree, but the whole area is quite bright. The light on the silk just makes the camera freak out a little, and it darkens everything to compensate.
