I've made roll films with paper.
Just cut a 60mm strip and roll it up in an old film backing. Because it is thicker than film, try maybe half the length (six shots).
Best is to position the start by the piece of tape... but don't tape it yet. Roll the film up - then tape it last. Otherwise you will get a kink or bubble.
I wouldn't stick it in a hassleblad film back - or anything that uses thickness sensing to give auto film spacing, but in rollfilm cameras with a red window it works OK.
I tested out Harman's direct positive paper this way.
