Make your baseboard more dramatic...add small pieces of trim to the top of existing baseboard, add a few inches and add another piece of molding. Paint the wall and trim white. This also works for crown molding too!
How to paint Baseboards on carpet: Use packing tape (painters is not sticky enough) to tape carpet and about a half inch of baseboard. Then use putty knife (pk) to slide tape under baseboards. Use pk to cut tape after it dries. Carpet rises to cover imperfections.
