Me and two friends took the Beginner's Knitting Class at Knit One after it was featured on Living Social. The staff was very accomodating in scheduling the classes, especially because they filled up quickly (only 4 students per class). They extended the expiration date for the Living Social so that everyone could schedule a class that worked for them.
I went a few days before my class to pick out my supplies, and felt very welcomed immediately in the store (referring to a previous review: believe me, I was just coming from work in my scrubs and did NOT look "well to do"). The staff was extremely helpful in picking out my supplies, which I appreciated because I was starting with absolutely zero knitting knowledge.
The class was two hours long, and our teacher, Wendy, got us started on our first project (a cowl). She made sure each student got one on one attention and answered any questions in a very friendly and patient manner. She fixed all the stuff we messed up (which I think everyone screwed up several times!). We left the class with the knowledge on how to continue to work on our project and how to fix a few simple problems we run into.
When I finish the cowl (hopefully sometime within the next two years... I'm pretty slow) I hope to enroll in another knitting class or attend Open Knit night on Tuesdays or Thursdays to learn how to start something new.
I recommend Knit One if you are interested in learning something new. The staff is extremely knowledgable and PATIENT... which is important when you are just starting out.
