"This would double as a projection screen for presentations " - be aware that a white muslin backdrop will not reflect light from a projector like a projection screen does, so the image will be less bright and less engaging to the viewer. Also, since cyc drops are generally huge, there is a tendency to 'go big' with the size of the projected image. This can work if you have a sufficiently bright projector (high lumen output - goal is 25-35 lumens per square foot on a projection screen, higher for a cyc like material), but most 'classroom' type projectors may be too weak to do a presentation justice. Because the cyc screen is far upstage, this tends to disconnect the audience from the presentation. A dedicated purpose projection screen that is closer to the main drape is recommended.
