I have several plastic templates and a few paper ones that I drew, I punch holes with a three ring punch and file them in a binder. I intended to organize them using some sort of system, but mostly I just stick them in the binder on top. I've discovered that one advantage is that I can easily see which ones I use most--they stay on top. That allows me to flip through the others every once in a while or when I want something "new." The small ones were a problem flopping around and tearing but now I slip them into sleeve protectors. Works really well for me.
