They wanted to go bold! They wanted an accent wall with complimentary colors! Which is fantastic because we love color, the problem was the carpets, which they weren't ready to rip up yet, were mauve. The brick was exposed on one huge wall, with windows trimmed out in hunter green trim. They were also redoing the trim, from vinyl white to a warm wood, so we had a lot of elements to work with in choosing a color!
Cutting in with two very distinct colors can be a challenge. It takes a very steady hand. Most contractors use tape but we pride ourselves on the fact that we don't. Using a 1" brush, and in some instances a "paint by numbers" brush we get a clean crisp cut in. I'm not saying that we don't use tape sometimes, for example if we're making stripes, or there isn't a clear cut in the architecture, but for the most part it's talent. Getting a sharp line, whether cutting into trim, ceiling, or corner, is what separates the true painters from the rest.
