I pay $15 to $35 / class. My LQS is the BOMB ... awesome group and wonderful folks.
The $15 class was machine embordiery ... and was one class. The "beginner's" ($35 was the price) class I took was scheduled for 3 nights, but the owner (who taught the class) stated that she would take whatever time it took ... ended up being 4 nights (2.5 hours / night). It was a period of 3 weeks (one class per week, one week had 2 classes) (So I got 4 nights of instruction for the price of $35. This included quilting history, different notions/tools etc ... and different kinds of material ... difference between Straight of grain, cross grain, bias, etc ... I can't tell you everything we covered. We were taught the proper way to use rulers ... the rotary tools ... and shown how to cut the material.
I paid $35 for a machine quilting class that went from 10 am to 4 pm.
The classes are great... they show you quite a bit, teach you from start to finish ... just a great group.
If I was you, I'd try to find a quilt guild or a LQS ... you will have better luck!
