One of my former students whom I absolutely adore has a very successful yarn store in Lansing
http://www.threadbearfiberarts.com/. They organize knitting groups. It really sounds like they have fun. I personally have never knitted, but I do like doing needlepoint.
Matt is a genius and just has the greatest personality. He majored in computer science, yet found knitting to be his passion. He did the website BTW.
Anyhow, if you need high-quality yarn, he sells it on his website.
Have funn knitting!
