So I'm going to back to the vendor where I bought my Janome Artistic for some intensive lessons (and repair as a tension thing broke off the machine). I can't get there until next Thursday. Some friends who are experienced longarm quilters suggested unthreading the machine and practicing following lines on paper or stencils that I've traced on to fabric. I feel silly doing it, but they said it helps to get the "muscle memory" down. I'm actually having fun with it. If I ever get my machine in working order, I think I'm going to love longarming!
