Working with Silk: What Should You Keep in Mind?

Dear users, dear authors,
what should you keep in mind when working with silk or silk yarn?
Let me know.

Does anyone else have anything to add?
I would have thought that silk would be relatively pleasant to work with at these temperatures?

So far, I’ve really only worked with silk-blend yarns—that is, cotton with silk or wool with silk in all sorts of variations. I’ve noticed that these yarns often have very different properties; sometimes they’re rather brittle, while other times they’re very pleasantly soft. They can also be quite warm. I’d describe artificial silk—that is, viscose—as a typical summer yarn.
