Well I purchased 2 x3 from Freestlye, but for my 9x12.. 3x4.. I cut all my own film for.
It's no big deal.. very few do it, have been doing it for years now.
In fact I was going to do th especial order from Ilford which can be very handy, but had none, so just end up cutting my own as I need.
Generally cut a group when I do it , and store it as such.
I happen to use s knife guillotine.. that I attached a wooden block to, to hold the film while it was being cut, that could be shut, with spacers made out of manila folders, to get the correct size. Works great. Give it a thought process.
Unfortunately my setup, is at home in Arizona and I am here in Texas with my 2x3 speed with a roll film back and an RB67.. so cannot take a picture of it for you.
