How do you paint a fabric canopy?

Is it an outdoor one? You could try fabric paint but check to see if it’s outdoor rated.

I would make up a batch of “chalk” paint using plaster of Paris mixed into what ever latex paint you like. (There are recipes online for DIY chalk paint) Then I would get the canvas fairly wet and use a brush or a roller to apply the paint. It will probably take several coats and it will look worse before it looks better. Make the paint kind of runny so it soaks into the fabric. Good luck. I am about to do the same thing with mine.

I have simply spray painted outdoor canvas with good results. Another option could be a latex paint mixed with fabric medium!

I just used cheap old walmart spray paint. Took 6 cans but it covered and 2 years later still looks good.
