On Sunday, my friend took me to Brooklyn General Store on Union St in Carroll Gardens. They also have a wide selection of materials and instructional courses. Although what I learned at Knit New York was invaluable, it appears that you get more bang for your buck in Brooklyn.
I also found some lovely little decorative buttons - some in great animal shapes - to incorporate into my knitting products. They also feature a "pattern of the month" online to give customers new project ideas. Here is a link to their blog.
