A pillow's shape, fabric, and adornment speak volumes. Rich fabrics, such as silk and velvet, and fancy tassel trims say "elegant" and "refined." Solid colors or stripes, as well as streamlined shapes, say "sophisticated" and "modern." Delicate patterns with ruffles and folds say "old-fashioned charm." Whatever the room, you can always redirect the conversation, swapping covers and cases for new styles.
