I used a canvas weight nylon/cotton fabric. It was pretty heavy and not knowing a thing about making banners and just jumping right in...I didn't use any type of fabric where air could flow through. We had a hard time keeping the banner from falling over :lol: Live and learn! I should have inserted an open weave (net??) strips or something where air could get through. The banner was probably 40" X 60" or so. I did do a large dolphin applique along with name of the team. It was cute but not at all practical.
