Clothespins are usually the item used to hang clothes out to dry or maybe to close containers. But did you ever think of using them to mark something on a piece of clothing? There's nothing more frustrating than doing a whole load only to realize you didn't take care of those stains. So mark them with a clothespin ahead of time and easily find them when you have time to take care of them.
There is nothing worse than losing a small stain on a large garment and being unable to find it or completely forgetting about it until after all your hard work. Clothespins can prevent that!
