How make cobweb?

I think there is a device called a "spinner" or something like that which hooks to a standard electric (or now cordless) drill. Into the holding container you put rubber cement and it "spins" out this wispy film in tiny web-like strands that will adhere to things and give the effect of cobwebs. Never used it so I don't know if the stuff is then hard to get off of everything but there is a rubber cement solvent that might help remove it from whatever you are using it on if that's an issue. Rubber cement will rub off of just about anything smooth but will adhere to fabric and such and never come out. The device is available at most theatrical supply places - Alcone Company in New York has it and I am sure other places too. As I recall it isn't too expensive for what it does. You could use that stuff that they make to put on Christmas trees that looks like fine white hair. NOT angel hair - that's fiberglass and makes me itch thinking about it. But this is some other fibrous kind of thing that is in fine strands that you could separate by hand and apply here and there with some care and creative use of the stuff. Hope this helps.

The fibers are long and stringy. Simply streach the stuff over the set.
