Im doing Hey Teach, from Knitty. The ladies at the shop said I probably need to make a smaller size since I am so knitting so big.
I guess I need to read an article about gauge, any suggestions.
I don't know about an article, but I would follow the gauge for that pattern. If your gauge is too big, go down a needle size and vice versa.
www.knitty.com has a great article on gauge
You can also check out the articles on knittingdaily that deal with ease, body vs garment measurement, and sweater fitting.
