First, a retraction. Sorry guys, I goofed but it's a small goof so you can relax. I originally said you needed two sheets of 12"x18" template plastic to make your template but you can easily make it work with one. So scratch that. If you bought two, I'm sorry. The bright side is you've got an extra sheet you can use for another project! Or you can return it to Joann's, either way.
To make your template, first print out all three sheets of this pdf file. When printing, be sure you do not scale the image at all, it needs to be at 100%. You don't need to cut your paper pieces out completely, just trim off the right side of piece A and the bottom of piece C, then tape the pieces together like the diagram below. Be careful to line up the black and red guides.
You will have something that looks like this.
Lay your sheet of template plastic over the paper template, lining the bottom edge of the plastic up with the bottom of the template. With your Sharpie, draw a line to the left of the template.
Cut along the line you just drew and tape the piece you cut off to the top of the larger piece of plastic, butting the straight edges together and making sure the plastic now completely covers the paper template. Make sure the bottom edge of the plastic perfectly aligns with the bottom edge of the template and tape the bottom edge to the paper. Use your permanent markers (black and red if you have them, otherwise don't sweat using the same color) and a ruler to trace the black and red guide lines on the template. If you're going to cut the plastic with scissors you should also trace the template outline. Don't worry about the stitching lines, they're just there to be pretty.
If you're using scissors, remove the paper and cut out the template. If you have and exacto knife and metal ruler, use them to cut along the template edges. And, voila! You're done.
