I have a frame very much like this and the biggest challenge I have is that my machine support doesn't roll evenly both directions. Smoother one way over another. It also has a small slider type lock for which way the rails roll. Mine doesn't unlock very easy and it is plastic which worries me about how long it will last. I like having the option to sew on the rails but still prefer handquilting when I have the time. I can't seem to go from beginner to even beginner plus!
