It's my belief that Pottery Barn's forte is it's textiles. They always have a wide variety of patterns, colors, and fabrics. They've also recently begun commissioning artists and print houses. For example, this Jillian Patchwork bedding ensemble was commissioned from an exclusive London print house (go to www.potterybarn.com for more info.)Too afraid to commit to a bright color on your walls? No worries, you can introduce them with one of their upholstered or slipcovered chairs. You can to online and select a chair, and then select the fabric you'd like to use on the chair. It's a great way to add visual impact to a room, without such a permanent measures at carpeting or paint.
You can also purchase fabric by the yard... so if you're yearning for some bold cafe curtains for your kitchen, you can make them yourself. And of course, they also utilize these fun fabrics by the means of decorative pillows, for those of you with even more commitment issues.
