Magic Touch Paintings on Instagram: "If you hate your brush cutting in, the Shur-Line edger could make the job a lot easier. It’s designed to run along flat ceilings, using small guide wheels to keep your lines straight and clean. This was my first time using it, and the results were solid. The lines came out sharp, but it took about three coats to get full coverage, which may have been because of the yellow paint. Personally, I still prefer cutting in with a brush since I’m comfortable with it.
