I subscribed to House Beautiful last spring after picking it up in a bookstore.  It is a fabulous publication!  There is information on all the basics, paints, wall coverings, window treatments, accessories, furniture, etc.  But there is a great deal of information from interior designers that the average person may not have access to.  There are a variety of styles represented and I always look forward to flipping through and getting my next inspiration.  There is also a column by Ina Garten (also known as The Barefoot Contessa on the Food Network).  The thing I like most is that the interior designers reveal many of their sources for where they shop for their clients and the paint tricks they use.
