There are often ways to add receptacles without making any other holes than for the new boxes or places that are hidden such as behind baseboards.

However there is what is called "surface wiring raceways". Wiremold is one common brand.

But it is not a very decorativce look.

Thanks. This is just what I was looking for. I clicked on the link you sent me, and also went to the wiremold web site. They give step by step instructions. Even I can do it. I found out how to get it too. Again, thank a lot.
