My favorite yarn store and now my regular s'n'b. Carries everything from workaday-but-quality (Cascade, Berroco) through hand-dyed indie amazingness (Zen Yarn Garden, Studioloo) and everything in between so I've always been able to find the yarn I need, or didn't know I needed. Great selection of books, needles (and notions. Staff are very friendly, very knowledgeable and approachable.
Short walk from St. Clair west station, which conveniently takes you past Starbucks at Bathurst/St.Clair, or the 7 Bathurst bus stops practically at the front door, get off at Nina street. Also, Gourmet Gringos just opened next door making for a fun double-header. Do not get guacamole on your knitting, though.
