I went to different yarn store located int Canton, going there by taking MTA bus from Fells point. it takes about 40minutes from MICA by bus.
the store called Balimore threadquarters, and they have different yarns, felts, fabric, and even threads!
They also had event called Yarn Bomb in the summer, which is an event to cover all the street trees and signal trunk with yarns. Also, the owner of the store told me that they always have different fibers exhibitions.
there are two more stores I want to visit in Hampden area, so I am planning on visiting them on coming weekend.
