You are getting a lot of feedback and might be a bit overwhelmed by it all. What it boils down to is that it is your quilt life and you should do what you feel is right for you. There is no right or wrong. the decision is yours and you need to make the one that you can live with. Don't do what you really don't want to do because you feel you might be letting people down. We all have had good/bad experiences with classes and what works for some may not work for others. Make the decision you want to make and don't worry about what anyone thinks. Quilting should be fun, not a chore to get thru. (This is my humble opinion.)
