Do you think the problem with their house not being cohesive is that they're moving from room to room and slowly working on it, and we don't really know where they're going with it? I like that their approach is realistic for most people, but I wonder if that's the real problem with the lack of cohesion.
I realize that working on various parts of the house at the same time can lend itself to a more cohesive result. For example, as one's style evolves and matures, the decor can be slowly changed out to reflect that in every room. In blogland, though, things are different it seems.
