I leave about six binding clips attached to the boom so it is always ready for me to hang anything from it including much heavier boards of foam core or pieces of acrylic.
The leading edge of the vellum (at the front of the scene) is also taped to the tabletop. That's required because the vellum is stored as a roll and, thus, has a strong curl to it that prevents it from lying flat on its own. If it would help to see a photo of that part of the setup, I can make that happen.
You could accomplish the exact same look using instead a sheet of white paper. The reason I prefer vellum is because, unlike paper, it is virtually wrinkle-free even when a klutz like me uses it.
