I needed a boat cover for my 14 ft Sunfish, so I decided to make one. The old, blue sewing machine in the craft corner did a great job. It only does straight stitches, but went through the double layers of Sunbrella with no problems. My newer sewing machine at home didn't work so well!
Threading the machine is a little different, so here are some photos.

I probably stitched at least 30 linear feet, no problems!
