Clear, vibrant paint colors can make any room look bright, warm, and inviting. Dark colors tend to make rooms look smaller and don't have a very homely appeal. Soft layers, such as the cushions and blankets mentioned above, can add a sense of warmth to your home. But you can also layer other items, such as rugs.
Gibbons recommends placing a new rug on top of an existing rug for warmth, texture, and interest. This works best when you combine a solid rug that is neutral and has a very rich texture, such as a natural fiber rug, with a flatter fabric rug that has an interesting pattern, he says.
