Home decor is essential to making your home a more interesting and beautiful place for you and your visitors. We don't like clutter so it's more of a challenge to decorate our tabletops more subtly, but it's still very important. If you like more decoration pieces, I would recommend Pottery Barn catalogs. Those are great reference and even if its not necessarily your style, you can take the items they've used to decorate, like clocks, frames, etc and just find them in the style you prefer.
Here's a simple outline of my thoughts on accessories for the home....
Bones = Walls/Paint/Trim - This part seems pretty basic, but the right/wrong color for your theme can make/break you.
Muscle = Furnishings - This is part of the first thing people see in your home, things like sofa, side tables, shelfs.
Fat = Accessories - You either like your decor lean, healthy or chunky. It's all in the preference, just don't go crazy.
Let me know how you see it.
