Thought I would add my two cents. LOL. I have had to take xrays of one kind or another over the last 4 years so I have accumulated a stack of those black xrays and they are really great for making templates. I always end up with "copies" after all my visits, and kept them for records, now I am cutting them up. And this morning I brough home three more envelopes and one of them has 32 sheets. Wahooooooooo. I'll hang on to those babies too as soon as appts are over, they have the real copies at the hospital. So if you ever get the chance to pick up your xrays, it works. :):)
