When you get a food stain on a fave piece of clothing you can toss it out, buy an applique to cover the stain or just stain the clothing with the same thing that orignally ruined it.
“Huh?”, you say. Let’s say you dropped a marinara-coated meatball onto your white dress. At the restaurant you tie your sweater around your waist to cover the stain but when you get home you wrap rubber-bands around sections of the dress and dip the dress in a pan filled with marinera. If the fabric allows it you could even heat the marinara pan on the stove to really saturate the dress. Remember tie-dying? Essentially that’s what you’re doing. If the dress was stained with grape juice, you would use grape juice to dye it and so on.
