Before you paint the walls it is important to paint the trim first. A painting pad is a very useful tool for painting along the edge where the ceiling meets the wall. It has guide wheels on it and will roll right along as you paint the trim. Next you will want to paint your woodwork including your baseboards and trim. When you go to roll the wall first take some painters tape and run it along the top of the baseboard to keep the specks that fly off the roller from getting on the baseboards. Use the paint pad to cut in along the trim before rolling the wall. For the corners use a corner pad to paint in the corner. Once you've cut in all the trim and edges you are ready to roll the wall. So paint the rest of the wall with your roller and you are all done.
