I recommend Wessco very highly.
We moved into a new/old house (in Ballard) last year. It was built in the early mid-century period and has some great design elements, but attractive window coverings were not one of them. We inherited the original heavy-looking fabric drapes in the shade of blah, and they were not improved by the way they were getting crapped out of these heinous brass thingamabobbers dangling from the ceiling. Had to go.
Luckily, we found some high tech and very fashionable replacements at Wessco. When their rep came by with samples and for measuring, she suggested we think outside of our comfort zone and try some of the colored options (almost everyone thinks they want white). We went with a neat soft gold honeycomb fabric in the front rooms and an espresso in the bedrooms/kitchen. It looks incredible - really really good. The window trims are a very rich oak, and the gold pulls out a lustrous tone in the wood. In the back, the espresso matches our cabinetry and brings the room together.
The technicians who put up the system were nice and professional, and a year later we are still very happy, so they did a good job on the install. The blinds have been good for thermoregulation and improved our house insulation. Good stuff at a good price.
