I can't find my pattern -- might have deleted after I made a mylar template (then had the hardware made one out of plexi for me --- I make a LOT of these for gifts and fundraisers). here's a link to a free one --- this uses a button, I made mine with velcro. You get the basic idea, though. Have fun with this!
