I've been winding small rolls onto large rolls, reducing the space that my 16mm film takes up in my basement. I'm also getting rid of soundtracks on 16mm mag stock. Not only is this stuff large and heavy, it isn't even very good. I hope to finish up this project tomorrow and then be able to clean up and re-purpose this basement room. With each rolls I reduce, I reclaim the core for future use. My drawer is now full with over 250.
