I am piling up a bunch of slide film these days. The labs have returned the transparencies to me cut only enough to get into negative holders. In other words the slides are unmounted. I am thinking about one day getting a projector and viewing these slides properly. How difficult is it to do this? It looks sort of thin between images and I'm not sure one cuts the film accurately. Is it easy? What about mounting them in slide holders. I need to learn about this so that I can decide what to do with these transparencies. Thank you for your help!
