I have a old white sewing machine and have sewed windows for my old boat on it.
It won't take as thick a thread as I wanted at the time but they lasted 3 years easy and I sold the boat

Also sewed a Tonneau cover for my truck with it.

Try taking some old jeans and double or triple them over and see if you can sew thur them, thats not much less then you will be doing with sunbrella.
