Why call her an idiot? I used to have a friend/neighbor and we shared everything. If one got a template we cut those lines and we each got a template. All you need is the lines, either the ones on the outside of the template or the ones on the inside of the template. Is called thrifty, not idiot. I like the one from the inside because it makes it easier to place it and more accurate location. There is always more than one way to use everything and not because she uses it different than most, it means she is an idiot. Let's be a little open minded here.
