 Hi, I'm Ty Pennington, and this is another one of Ty's Tips. Using the right fabrics when decorating can really help define a room's sense of style. But whether fabric is first or last on your list, here are a few suggestions to get you started. Pick up fabric swatches that are sized in proportion to how they'll be used in the room. For example, upholstery fabric would be the largest swatch, then window coverings, then pillows and so on.
