Classes are fun, great way to learn...
I taught myself how to knit and needed some help learning more complex stitches...the internet can only take you so far. The classes were fun once they got started...just pray you don't get some frantic, panicky student in there, very annoying...but you Do get a lot of personalized attention and whenever you run into a snag the instructor will very patiently walk you through it. i learned how to make a hat in 2 classes, and a blanket in another.
the selection is pretty pricey but i think the classes are a reasonable price. if you want to take lessons, but don't want to make this the most expensive hobby ever, buy your supplies at Michael's.
($12 a ball of yarn???) If you're total newbie, then just buy your stuff there and don't worry about guessing what's what.
finally, if you are overcharged (which i was) don't let them give you a credit ticket, if you lose it than you LOSE the money...not happy about that at all.
Overall, i think this is place is great, especially since it's next to a couple of bars; sloppy drunk guys see a group of ladies knitting a yell out ...""heeeey, there's a housewives party in there!""
