If home-time has given you a chance to spruce up your home with a little paint job, however, when you open your saved paint it has clumped in the can since it’s last use, don’t fret! Stretch an old pair of pantyhose over the opening of the can as a screen. Secure with duct tape. Now slowly pour the paint into a paint tray. The nylon will have filtered the lumps and clumps so you will be left with smooth paint for your project.
