A note about painting...
After you put on your first coat of paint, clean your brush out thoroughly. Never paint when it to too cold, and never leave paint out in freezing conditions. Once the first coat has dried, lightly hand sand it down with some 220 grit sandpaper. This is because the wood fibers like to really stand up after the first coat. So, what you are really doing is lightly knocking them back down again and getting ready for the second, smoother coat of paint. When you start your second coat of paint, you will have a nice, clean brush that can make smoother, cleaner strokes and no lines. Use enough paint to cover the material, and never overbrush it. Once it is coated, move on and let the paint level itself out. Always take care of any drips while it is wet, and if it dries, you can always go back with a knife and sandpaper and smooth over those parts.
