Congrats!
Unfortunately, Storehouse and Bombay, where we got a lot of things, are out of business. We recently bought a sofa from Hamilton's Sofa Gallery (Rockville). We don't have it yet, but they have a good selection in a number of price ranges.
We wound up buying quite a few antique pieces from Pritchard's in Kensington. Kensington has an antique row (Howard Ave.) and if you are open to that, some of the stores have really nicely refinished pieces. We got our dining room set and two dressers there.
We've also bought a few things from Crate & Barrell - our bed and a rug, specifically.
The Rockville Home Goods also has a lot of furniture. It is hit or miss, but every once in a while you luck out. We bought out TV console there, as well as a wine table and tons of accessories, including our LR rug, which we saw in a rug gallery for twice the price.
Good luck and take your time!
