If you have never been, I would definitely go visit the old space while you can. From the street, it really seems like you're in the wrong place. A long-suffering friend who visited with me described it as a 'yarn speakeasy' and that nicely conveys the sense of entering into a secretive world. The yarns themselves are just as magical. Just read the description for the glass marbles (?!) they have on their website:

"So, here is another beautiful item, which will make you wonder "what am I going to do with this?"
It is a marble. We all need a marble. We all need a "marble" to keep our marbles if you know what I mean.
Please take a look at each one of them very closely. How beautifully crafted. Each one is different. It cannot be repeated. Please take one. Keep it in your bag. Take it out once in a while and look at it.
It will make you feel good."
So funny but so sweet! It's a great, weird space, full of great, weird yarns and ... marbles.
