I found a great website that will let you plan your room with out having your hubby move your furniture around all day, even though that's fun too. This would also be a great tool for anyone moving to a new house. You can put in your room and furniture dimensions then move your funiture around with the click of a button.
It's called planyourroom.com I found it on the Smith's Furniture website. When you are done with your plan you can just email it to yourself. You don't even have to sign up for anything.
