Used a foam weather striping sandwiched between the window and the canvas.

Did not use a single stitch, would use 3-4 ft lengths which occasionally would break too. Look in the last pic in the renntech discussion you can see how I started a new piece of thread.

The window is not completely water tight, there are a couple small places water will seep through on very rainy days.

I did not use any glue, but I did apply thread sealant.

Good luck.
