I need a software (a free one) to decorate my room. Well, I have your answer right here. That is interior DECORATING, NOT interior design (huge difference). I don't know of any software but there is probably a inexpensive one floating around the clearance bins at Best Buy. Just pick draw out some options for what you want instead of wasting your money on a software program that just shows you different styles of wallpaper or furniture. Interior designers primarily use SketchUp or AutoCAD, but it sounds like these are way above your needs.
