There are a LOT of photos with this, so I've uploaded all of them in five separate posts, and I'll add the text next.
You'll need a sheet or two of graph paper to get really even measured cut-outs, a stiff sheet of paper or cardboard to make the template, scissors, glue, stapler, some paper to make the envelopes out of (I use scrap paper) and a pencil.
Trim the graph paper along marked lines so that you're starting from exact squares.
Measure how big the envelope needs to be. It should be about a quarter inch larger than what's going in it so it goes in and out easily, larger if what you're putting in it is thick. I think I'll make some envelopes for all my money.
Cut exactly, using the grid lines as a guide. Use the first graph paper rectangle to measure a second one.
Cut two identical rectangles from graph paper.
