Painting projects can get messy, not to mention expensive. Solve both issues by creating your own paint drip catcher. To make your DIY efforts neater and more economical, all you'll need is a plastic lid from an oatmeal or coffee can and a knife. Simply cut two small slits to create an X in the center of the lid and slip your brush through. This easy trick catches problematic drips fast and is practically free. Give it a try — chances are you'll never want to paint without this handy helper again.
