When painting walls and ceilings, it can be difficult to get an even, close edge where planes meet. It's especially difficult if you're painting with a roller, since this tool is large and often unwieldy. This is where the term "cutting in" applies. It describes the simple method of painting the edges to get that nice straight line we all want in our painting projects. Usually, cutting in is done before covering the larger surface area. A 2.5-inch brush should do the job.
