Blog about how some trends do not have to be a one-time deal. For example, blog about how retro style for your home is a great way to decorate a den or family room without ever having to redo it again. You can always add retro pieces as you go along to change it up, but that theme can stay around for a long time. Shabby Chic is another great trend that is great for a formal dining room and one that can stay for a long time, as well.
