When you are painting with a roller, while you take a break, you can keep the paint from drying out by sliding the roller into a clean Pringles canister (these are the perfect size for a paint roller). Simply clean the canister by wiping the interior with a damp paper towel. Place the roller inside, leaving the handle on the outside. Cover the opening with duct tape. This will create a seal to keep the paint on the roller from drying out for several hours. So, no extra roller cleaning!
