I got a couple rolls of Foma 400 ISO 120 the other day and decided to try them out today. I'm new to this format, but I've learned that 120 film typically has a lick-and-stick type adhesive on the backing to prevent it from unspooling after being shot. Strangely, despite being the same stock, purchased at the same store at the same time, my two rolls of Foma were incongruent in this area: One had lick-and-stick capability, and the other did not seem to.
This caused me some anxiety as, in daylight, I fond myself without assurance that my roll would stay closed. A quick glance in my glovebox offered an immediate on-the-spot solution.
Turns out the ear loops on the stupid paper masks, of which we have piles upon piles, are perfect for gently preventing these loose rolls from unravelling. I tied one around the licked-and-stuck roll as well, just for good measure.
I wonder if anyone's figured out some good DIY projects for those clear plastic face visor things. Other than Repo! The Genetic Opera cosplay, of course.
