Cutting in with Aura

Most of the time when you are painting interior walls, you want to cut in around the edges with your brush and then immediately roll the open part of the wall so that the brushed part and the rolled part all dry together.  In other words, you try to keep a "wet edge" between the cut-in and the rolled areas.  Depending on the humidity, you can sometimes cut in an entire room before starting to use the roller, but most of the time you must cut in and then roll one wall at a time.
