If a room in your house lacks character, by simply placing some fine art prints on the walls can actually make quite an impact. Wall pictures are a necessary accessory in your home and are great to tie in with the room's style and color accent. Before you go off to buy some new pictures for your walls there are a few things you need to plan and decide upon.Maybe you’re redoing a family room that will be chock full of children, pets and peanut butter cracker crumbs. The fabrics, paint color, even the lighting for this action-oriented room will be completely opposite to the needs of a tranquil bathroom, just as the functional design of a modern home office will differ from a cozy guest bedroom.Design pros use a maquette to map out the dimensions of a room, outline the furniture, assign placement to windows, doors, outlets and other immovable objects, such as a fireplace, to know how and what to design.The maquette can be a simple piece of paper with the room drawn on it, featuring measurements of each area for quick reference. You can also place little shapes of furniture on the maquette to "move" at will as you work through your design.
