You can use canvas fabric for outdoor projects, but waterproofing and long-term protection methods should be considered. Choose the right fabric – cotton canvases are lightweight and stretchy, while linen canvases are strong and durable. Opt for a better quality acrylic paint with brilliant colors that won’t fade in sunlight. For smaller items like pillows or cushions made from blue jeans denim material, add an extra layer of waterproof sealant over the top once you’re done painting for increased longevity outdoors!
