I have a crafting question. I have polyester oxford cloth banners I want to paint stenciled letters onto using acrylic paint, and I'm wondering if I can just paint on it without treating the cloth, or if I should set the cloth by sizing it in some fabric glue & hot water (1:1) and air dry it a couple days, like you would, for prepping a canvas for painting? Since I'd be rolling up the banner and using it over and over once painted, I'm wondering if treating the fabric this way would help with durability as well as making the paint adhere better. Pic is just an example of what my banner looks like. TIA #asknostr #crafts
