My first quilt was a huge Trip Around the World with directions out of a magazine. It was cut with scissors and took months. My second was a class - Log cabin in a day, with strips ripped. After that, rotary cutters came out, and I took my dinosaur to a strip piecing class to learn all the new techniques.
I like learning new techniques and experimenting with new stuff. I would not be interested in a class just to make the exact same thing as everyone else. Like so many have already said, there is so much free information now
Most of the classes I've seen lately are geared towards selling pricey doo-dads. In order to attend, you have major investments in specialty tools. The days of using a single ruler as a multi-purpose tool are gone.
