Here's my first attempt at stitching. I started with a 3/8" strip of solartex then folded over (and ironed) the edge to make a 1/8" double layer. I then laid down two of these strips on a piece of tape that held them in place. Next I marked the position of the holes and then did the stitching with a double strand of sewing thread. After I finished the stitching, I turned it over and very lightly scored the tape so that I could remove the tape from the edge of the solartex. I then ironed this onto my practice piece.

It still needs work. This is the same stitching pattern as on Craig's Pup but done this way you only see half of the diagonals rather than the V pattern (which I prefer).

BTW, I tried simulating the grommets with white glue and a tube (rivet style) but that attempt failed miserably. []
