If you're using a paint pail such as the Handy Paint Pail by Bercom International, it will have a little magnet on the side of the pail. This little convenience allows the brush to fasten to the magnet by the ferrule and have the bristles dipped in paint, keeping them wet while you go have lunch.
Other pails may have a separate compartment that the brush slides into to keep it wet while pausing. If you don't have a paint pail with these features or are working from a paint can, just find a way to leave the brush bristles in the paint.
NOTE:
When you are storing the brush, make sure you do not place it too far into the paint, overloading it. Remember to only place 1/3 of the the bristles in the paint!
