I made these a few years ago for myself. They are full size 8-1/2 x 11. I took one and shrunk it down and got it stuck inside my lid so it's always in site. I even had other techs take pictures of it for themselves to use. You can print these out or download the file and shrink it. The one on my tool box is about like an index card size.
I also have a laminator here so of course mine are laminated.
