Pinhole sharpness.

Well, I got my pinhole pictures back, and the exposures were almost dead
Sharpness, on the other hand, left something to be desired. The
material that I made the pinhole in was about 1mm thick. I think that
this might have caused some reflections and so forth, but I'm not sure.
Can anyone offer suggestions for improving the sharpness of the image?
Does it have to do with the pinhole size, or something else?
