Kelly: Try your local hardware store. The screen material usually used is actually a nylon or plastic screen that is normally used for window screen replacements. The last time I bought it, it was on a roll, like fabric, and the sales person cut off the amount I needed, by the yard. Stay away from metal or plastic-coated metal screening material - that's too harsh for what you need!

We have just acquired a vacuum with HEPA filter and need to find some type of screen to place between the vacuum nozzle and the artifact when cleaning is necessary. I have had no luck with the usual product catalogs found in most museums and would appreciate any help the list could provide me. Thanks in advance, Kelly Wilkerson
