It wasn't so much going from mechanical to computerized, as going from crappy to quality. I went from a 1990's basic Singer (junk) to a Baby Lock Quest Plus. Immediately, the accuracy of my piecing improved. I was then able to start machine quilting, something that Singer never did decently. I'm still very new to machine quilting, but I've added Berninas old and new and found that I enjoy machine sewing more than ever before. I now look for opportunities to incorporate deco stitches into projects and am starting to use the machine for appliqué and quilting, which I used to do exclusively by hand.
