You've gotten some great advice from other quilters. I want to encourage you not to give up though. I had a stroke and it took me several years before I could "multi-task" again. I, like you, would be so confused but with lots of concentration, I am back to teaching quilting again. Just stick with it. Try to stay as organized as possible so you don't have to use all your energy finding stuff and just enjoy your quilting. Don't let yourself get too discouraged. It's worth the effort.
