Sunshine cloth? What are they and where do you get them from?

Also, with a lot of my designs, I use stainless steel cable, but it's nylon coated.... would it still damage the pearls? I haven't had any complaints yet, but I just want to make sure I'm doing the right thing. I find it's much easier to deal with, and fairly easy to conceal the ends, etc.

Can anyone help?

Thank you!
