This screen is composed of 30 silk threads per inch which contract to about 55 tpi because of the twisted shape.
Currently I'm fixing three of the six bands needed. It takes quite a while to adjust the threads' tension and the density at the bottom. Lots of tiny movements, but after a day I feel as tired as if I'd really worked... Yet - I had a visit from a small assistant, probably interested in helping me: a spider (can you see it on the image?).
