Tired of trial and error? I know I am. Arranging and rearranging furniture only to go back to the original placement. I just discovered Floorplanner and it looks pretty promising. It's an online tool that allows you to quickly and easily create floorplans. You can see it in 3D and add + place things all the way down to plants. Once created, you can save, send and print your designs. And, it's free.
