I’m not the OP, but I couldn’t leave y’all hanging with no moss.

Fair comment. I used gaffer tape a lot at the beginning of my journey because it was convenient and available, but everything I built fell apart eventually, so I started using cloth duct tape. I recently discovered aluminium duct tape which is genuinely amazing. It’s like regular cloth duct tape, but it can be shaped really precisely, and it holds it’s shape even if everything else falls apart around it.

Duct tape and cardboard solutions to questions like “How do I get these two pieces of photography equipment to work together?”
