Thanks Alphonso Harrison! Great question. Often your local art store, like Michael’s here, will have full sets of unique brushes and application tool. Shop for a 1-inch tool similar to your applicator and follow the same direction as the closest pattern applied to the wall. Or, use a 1-inch chip brush and use a stippling motion to pull up the paint in the cut in area. Delicate surface tape will be your best bet for creating a straight line. Hope that helps, Pat InPaint
