Use a plastic bag to keep paintbrushes fresh
Unless you don’t complete everything you intended to paint in one session, wall painting may be a wonderfully soothing pastime… unless you run out of time. If that happens, you’ll be left with a brush that’s as hard as steel after the paint has dried for 35 seconds.
Don’t get carried away, though; be creative. If you wrap the paintbrush in an airtight plastic bag when you’re finished with it, it’ll keep fresh and functional for your next project – even if it’s months later.
