I understand about the cost of taking a quilt class. I remember when I started quilting in the late 70s there were no quilt shops around. My initial thought was that quilting would be a cheap hobby because I could use all my garment scraps.
That being said, I think most LQS have a variety of classes that can be tailored to a variety of budgets. Our shop has machines for beginning customers use during class at no charge other than the customer purchasing needles, a bobbin and thread. Some class quilts can be tailored smaller to learn the techniques without starting out at a bed quilt size, etc.
Quilting didn't turn out to be cheap but it has been the most creative thing I've experienced. There is always something new to learn. Of course, the people I have met are the BEST! And I never would have dreamed that a global quilting community would have been possible when I started quilting.
