Watching a prior thread about the age old question regarding the best dark cloth to use...I wanted to inject some different thinking, rather get in line twenty-five posts back.
I learned long ago, from using my huge Linhof Kardon 8X10 in my studio, that a wire frame that holds the dark cloth over the GG of the camera is as important if not MORE so, that the material that any dark cloth is made from. It works in daylight just as well as in the studio.
Presently with my mint Technika V, I have a wire frame, bent by hand, that attaches to the rear assembly of my Technika and gives me a huge canopy that I can close easily with my free hand or with wooden close-pins (Ace Hardware), Velcro, or any other way.
My 8X10 Kardon had a twin- hole system in the rear standard, that accepted the 3/16" SS wire frame that 'hung' the dark cloth over the GG which minimized the tendencey for your head..moving out of the GG area....to pull your cloth off of the camera.
I've also made a dark cloth hanging frame out of coat-hanger wire, and bent it to shape, and it works wonders.
Take a deep breath. Grab a pair of pliers, bend a frame to fit on your rear standard, and try it.
I'll bet you will like it. There is no perfect dark cloth. Almost any type will work just fine, with a hanging frame. (:-)
