I love classes at both the LQS and the large quilt shows. Because I make it a point to take new classes in areas of little expertise to gain more knowledge and skill. Knowing this I don't expect my work to be the best in the class since it is new. So I think if you go with the mindset to not be hard on yourself you will have a better experience. I usually go by myself but quilters are so nice it is usually easy to meet new friends and sometimes you can get some tips from more experienced classmates. There will always be snobs wherever you go but you can't let negative people ruin a positive experience. I think most quilters are way to hard on themselves. I also wouldn't worry about peoples fancy machines they sew the exact same thing so you will make a lovely quilt whether you have a 50 dollar machine or a TOL. I have a low end and a nice machine and I sew on my Walmart brother all the time and love it just as much as my big machine. And I used a small machine for many years before I upgraded and I did just fine. No real genuine person will look down on you for what you are using. Quilts are made with love not money
