I am looking for information for training staff on the mirror method of fitting. I use this method myself, and had some wonderful graphics, etc which I used in previous training sessions, but the files have done a runner. I simply can't locate them.

I've done a fairly exhaustive search online, and haven't been able to locate anything copyrighted or not. :(

Does anyone know where I may be able to find this information?

Thanks for your help.
