I just wind them on a lot after the last shot (this makes absolutely no sense, still I keep doing it for shits and giggles), then open the back & take out the spool carefully and not in direct sunlight obviously, putting a finger on the wound-up film so it can't come loose / pull on the end a little bit so it's tighter and tape it. It's not rocket science.
Oh yeah, and 6x9 gives you only 8 images on a roll of 120.
I tried pulling the wound film tighter but wouldnt really go for some reason. I have another roll of the same film (Clocktower cameras gave me 2 for a fiver) so might just blast through it one sunny day and try again
