Superfast folding jig

First, have a look at how it works

What you need: 1 manila folder, masking tape, ruler, square, knife or scissors
All pieces are 6.5" tall. Since the width of the cloth is 7.5", this leaves 1/2" of the cloth hanging out on either side. The widths are as indicated in red. These are not very critical. Just make sure all angles are square.

dxf cutfile if you want to cut the pattern on a laser cutter. Tight fit: 1/8" margins.

First the base. Tape one of the 3/4" strips on one of the pieces, in this case 'base 2' Check for square.
Tape the other piece in place. This last joint is the one you take loose when splitting the jig to remove the folded and sewed cloth.
Flip the base over, and tape the other 3/4" piece in place, near the center of the RH base piece (base 2). Check for square
Pre-fold the template, also fold over the 1/4" seam

The template is page2 in this pdf

Seam down, slide the template against the edge, and hold it in place with a bit of tape.
Tuck piece #1 into the fold, aligning the top and bottom edges, and tape the right-hand edge down onto the base.
Tuck piece #2 in from the left and tape it down
#3 is tucked in from the right, and #4 from the left
Unfold everything, ready for use.
Here is how to use it
