Waterproofing fabric spray
Whether you are bored or artistic, one way to express your style is by doodling on plain canvas shoes. Permanent markers or fabric markers are best for this project because they are formulated to adhere to fabric with little or no bleeding. However, a heavy hand with the ink or a little too much detergent in the washing machine will cause even the toughest craft inks. Keep your colors from running by coating your artwork with a waterproofing fabric spray.
Brush loose any dirt and clean the shoes in your washing machine with a load of towels before drawing on them. If the shoes are not clean, the waterproofing will not make a permanent seal.
Allow the permanent marker ink to dry for 24 hours.
Hold the waterproofing fabric spray at least 6 inches from the canvas and spray in long, even strokes. Spray the entire shoe, not just the area where you applied the permanent marker. If the entire shoe is not sprayed, it will stain and wear unevenly.
Allow the spray to dry for the manufacture's recommended amount of time.
Apply additional coats as desired. Some waterproofing sprays allow for multiple coats, while others become shell-like the more coats you apply.
Purchase a waterproofing spray intended for outdoor canvas for the best results. If you have already drawn on your shoes without cleaning them first, brush the canvas with a stiff-bristled brush to remove any dirt from the surface. Do not wash them with water or the marker may run.
