I found this on line. I'm going to use it for color charts for my pencils. It could be used for a lot of different charts. It's better than having to draw the lines myself. I'm putting each page in a page protector and then in one of those soft 3 hole folders they sell in most places. I have a few different brands of colored pencils in Global Binders. This eliminates my having to look through each one to see which green I want to use. Someone had suggested charts and I thought that would work for me. So, if you like the idea, here's your squares all ready to print.
