A lot of medical offices are changing over to Electronic Medical Records so they are getting rid of their file folders. These are a great weight to make templates. I print the templates out then glue the whole page to a folder and then just cut out the templates. They hold up to rotary cutting if you're really careful but I just trace around them and cut them out with scissors. Can you tell I learned to quilt a loooooong time ago?
If you know anyone who works in a medical office, you could ask them to save their old file folders for you. They just cut the name off and throw them in a box for me; of course, it helps that I work there every once in awhile but I bet they'd save them for you if you asked. Just a thought.
