Thanks for this tutorial. I was just thinking about doing some templates. We go through about 9 gallons of milk a week so I am going to cut them down and use that plastic. I got a nifty little tool to open plastic packages at the dollar store. It will be great to cut down the jugs. Finally a use for all of that plastic.
My Mother in law gets xray film from out Dr. to make hers. It works great too.
