Another useful thing, as well as doing stuff in the right order, is to label all your film-holders. Use masking tape or something, with (for example) both a letter for each type of film and a number to keep track of what you have shot, what needs to be changed out etc. etc. Shoot in alphanumeric order and make a quick note, even if there is nothing special to note down, so everything at least 'feels' under control . . .
Almost all my sheet-film experience was working in a lab, but last autumn I made myself a point-and-shoot style 4x5 out of foamboard. Initially it was a pinhole, but then I got myself a Fuji 150mm in a shutter and made a double-sliding-box scale focus variation on the pinhole. No movements of course. I am developing new ways of making mistakes too.
