Keeping in mind we are going low budget here. We are building a stage in front of our existing screen. We need to have a stage entrance and the only way there is room to do this is by cutting a doorway in the lower corner of the screen. We are planning on building a frame for the entrance and re-securing the cut parts of the screen to this to maintain screen tension. The entrance would be a curtained entrance (not a door). Has anyone ever done anything like this or have opinions?
