Has anyone tried this. I know it will not last forever but it would be pretty easy to sew up and cheap too. W
FWIW, I had a sailcloth awning for my catboat. Since I only used it while at anchor, it lasted until I sold the boat. I don't know if the current owners use it or not. Of course, a bimini is up most of the time.
As long as you used a good thread that has heavy-duty UV resistance, it should work just fine, if not last quite as long as Sunbrella.
Interesting way to recycle! :)
Sounds worth a try. I have plenty of old sails, good thread, and a Pfaff 130 sewing machine. Back in '82 I used sail cloth with epoxy to repair my car body. Those patches lasted many years.
