Hi All,
Yes, American Thermaform is still alive and well. They are located in
California and their phone number is:
800-331-3676.
I use three-hole punched thermaform all the time for various things and I
believe they have fan-fold for braille printers as well. I purchase it
prepunched from them in boxes of 1500 sheets I think it is. Anyway, it's a
better quality than I remember the older stuff being and does not make your
fingers tired when reading like the older stuff used to do.
I find that it works well either in a brailler or with a slate. I use the
brailler most of the time, however.
