In the window coverings industry, there are both hard and soft "treatments". Blinds, shades, and shutters would be in the former category, and most often provide a much needed light control function for a room. Once that need is identified and defined, it is easy to know what product is best.
Of course, the many products available today are also gorgeous design choices as well - especially when paired with a beautiful soft treatment like drapery panels or an up to date valance.
The Coulisse nature collection is at the top of my list. Their XL pleated shades are also a designers dream. Each of their products is an exceptional upgrade to the traditionally styled shade or blind. (These amazing collections are now available at dePasquale Designs.)
