Make sure that you have the right machine for the job. I have just purchased a Juki TL98 machine from my friend who had it sitting in her sewing room gathering dust as she bought a long arm. The machine is amazing and perfect for what I do. It's fast powerful and has wonderful stitches and a great thread cutter. In the last two days, I have quilted a large single quilt and a large crib quilt. There's been no jamming, growling breaking thread and sore arms from trying to force my old machine to quilt. My quilt tops were stacking up because machine quilting was so frustrating, hard and slow for me. I just can't believe the difference this machine has made.
