This is one of the most disorganized stores I've seen. Yarn is piled onto shelves by type, yes, but just because there's a shelf of worsted-weight wool by Plymouth here, doesn't mean that the adjacent shelf will be worsted, wool, or Plymouth. There's half-empty bags of yarn lying on the floor everywhere, too. The messiness isn't crucial, but a bit off-putting because it's hard to find things.
Also -- and this is a deal-breaker for me -- there was no laceweight yarn in the store besides the mohair varieties.
This store is very cramped and small, which I didn't like. They also tend to carry way too much novelty yarn for my tastes and not enough solid-colored natural fibers. I didn't see much laceweight yarn, and they only had one kind of sock yarn (self-striping). I was disappointed. The ladies there are quite helpful, though.
The store is just one room, and, at first, seems to have not much in it. However, browsing around, I found a little bit of everything! There were all kinds of yarn weights, which was great, because I was looking for lace and sock weight yarns. This place carried solid-color sock yarn, which earned it a big plus from me. Overall, solid colored, non-novelty yarns seemed to predominate, which was, again, a plus as far as I'm concerned.
The store had a nice and varied selection of fibers, from wool to cotton to bamboo to corn to porcelain to alpaca to acrylic. There is also a solid selection of needles, notions, and books/booklets.
Finally, the store's owner was very helpful, but unobtrusive. Overall, it was a pleasant yarn-buying experience.
