I hear your pain... and everyone has given some good suggestions. I just want to encourage you to ..... Not Give Up!! I taught sewing for many years before I ever made a quilt. And there were many of my students that struggled..... but after awhile, they got the hang of it and turned out some beautiful items. I'm hoping that's the case with you as well. I think the one-on-one lesson would be a good one if you can find the right teacher. Some teachers expect perfection..... others just have a way to work with you until you get it.... if you know what I mean.
So, I know you're discouraged right now.... but hang in there. We all have different learning curves.
