Hi I'm technical manager for a production in a small local theatre and we have a shark tooth gauze we intend to have at the front front of the stage fixed to the front of the lighting grid above the stage. We need to use this gauze during the show for projection and effect but for other scenes we need to 'fly it out'. However we have no flying space with being a small theatre apart from about a metre in height where the grid is located. What are my options for raising and lowering this curtain? I've heard of roll drop systems but these are supposedly not meant to be used with stretching materials such as sharks tooth gauze? Any help appreciated.
