Isn't it amazing that our personal reactions to taking quilting classes have so much to do with how we felt about school? I am an assertive person, but never wanted to look dumb in school. It took years to overcome that fear of asking a question when I thought everyone else in the class 'got it'. Then one day it dawned on me that someone else almost always asked the question I wanted to ask and bailed me out.
Since my fear was holding me back, I mustered the courage to ask questions. At first, it was difficult to do, but it served me well for the rest of my life. I still ask the dumb questions.
However, I rarely take classes for quilting. My color vision is a big factor in that, as most or the quilts I might want to take in a class are complex with too many colors/fabrics in them. Too many colors/fabrics confuses my brain and frustrates me to the point where the quilt joins UFO pile, never to be finished.
