When I first started shooting 120, I have to say it took me a while to get the hang on the very different feel of the package compared to 135. One thing I like, is the discarded "fishbone", the 120 plastic roll spool. Ofcourse one will keep a couple as spares so to be able to load the backs with fresh film, but being a new guy into this whole medium format business, it felt... well, strange to throw away a perfectly nice 120 spool. I mean they are so cute! Ahem. Anyway. So, what to do with them? I have now a whole bag of them and keep filling it up as I shoot. One day it will overflow and I will need to find a bigger one and then a bigger one, until I need a storage space for them! I will choke on plastic 120 spools! The only uses I have think of are: - Pet toy. My cat loves the spool tied to a cord. - Necklace. String 'em together for a post-modern neo-hippy statement that "film ain't dead you digital pussies!" - Roll them on the floor and enjoy as people trip on them. Good for escaping the cops after a bank heist. - Fodder for hand catapult. I haven't tried it so the aerodynamics of the plastic spool could be bad. Could be useful as a weapon during a riot or a football game. - Material for a sculptural art piece What else?
