Start with a clean room. If you have fabrics already in the room, you can click on the [Reset Room] button to clear the room.
You can click on the sofa, chair, each pillow, and the drapes. As you select an item, it will tell you what is selected at the top right.
Then, you click on the fabric you want to add to that selection and it will show up on the selection. It will also tell you at the bottom of the screen what you put on that selection.
Once you have all the fabrics on the furniture, pillows and drapes, you can change the wall color by clicking on the button to the right and clicking the color from the color pallet.
Now, you can change the floor. You can select from three hardwoods, three tiles or a color pallet of carpet. Just click on the button beside Change Floor and then click on the drop down menu. The choices will show below.
