1. There is a parking lot next to the building. It is small, but has high turnover.
2. There is a flight of stairs, no elevator.
3. It is just a few blocks from the Bethesda Metro station - and just 2 blocks from the street-level elevator.
4. It is the door next to a small restaurant, and you need to look for it. I've accidentally gone into the restaurant twice, and I know better!
Once in the actual shop (be sure to look at the pretty shawls on the way up!), there's a lot to see! There aren't as many books as there used to be - the advent of electronic pattern sales has caused a downturn in both sales and publishing - but there's a good selection in the Book Nook.
There are indie dyers, Chiagoo needles, lots of notions, and more yarn. And more yarn.
