Maggie,
I would suggest a polaroid film holder (to test your exposure-and for final pics), and if you are going to use sheet film and load it yourself, go with new holders, such as the Lisco brand. They are inexpensive and reliable. You can also go with readyload sheet film, but it costs more
being zone plate, one pinhole. Both images looked great. I plan on taking many more over the next week, to put it through its paces.
The film back attaches with 2 rubber bands. Nice low tech solution. I'm planning on carrying extra rubber bands when shooting with the camera.
