Peg Leg Vintage for mid century modern.

Frederick has lots!

Any place with a large retired population.

I love Evolution on Route 1 just outside Old Town. I have bought cute things there and have seen so many things that made me wish I had not already purchased elsewhere.

They are nice so happy to give them a shout out (although hate to let my secret out).

You might like Random Harvest in Bethesda.

There used to be one next to cafe deluxe on wisconsin ave across from the cathedral-- not sure if it's stil there.

Otherwise in Georgetown, I would think.

Gallery St. Elmo in Bethesda
Antique Row on Howard Avenue east and west of Connecticut in Kensington
And do a search here, I posted a much bigger list at some point

All the furniture consignment shops I know of went out of business. Why don't you go to an antique shop. There are lots in Frederick. If you want mid-century modern then there are used furniture stores on U Street. But consignment isn't usually how things are sold.

If you just want used furniture, check out craigslist or ebay.

We are furniture shopping and interested in consignment, don't quite know where to start. Please post good consignment shops - close to NW DC ideal but willing to travel for a good place.
