I have a really good friend that always likes to change the theme of her home.  You never know what it is going to look like the next time you go to visit.  The last time I talked to her she told me she was going to look for some Modern Coffee Tables to go with her new theme of the month.  I have no idea how she can afford to change her themes so often, but I believe she gets a lot of used furniture and mixes it in with the other styles, although she will never admit to it.   She is crafty and does do some refinishing as well.  However it is that she does it, she always makes her house look spectacular.
