Go for it. I took lessons last year to learn about quilting and I had never sewn before. I am a learner that needs confirmation after I do something to ensure I did it correctly. You can imagine how my teacher felt since most of the other students were more experienced with sewing machines than me. It was a good experience and I continue to take classes online as well as the local quilt stores. It is always great to learn and especially from those with experience as they have great tips.
Much like the members of this board. Remember that everyone who takes classes is more interested in learning than socializing or least that is what I have found so far. Wishing you the best in your classes!
