I waited for years to purchase mine, it just seemed so expensive. Now I wish I had not waited so long. I love it. It really makes a difference. No more little puckers on the backs! I hated getting to the point on a project that I had to quilt it , because as good as I was getting onthe piecing , the back would show I was still ... an novice. I would spend hours smoothing , and smoothing and still little puckers. My walking foot and spray basting changed everything.
