It sounds like it's going to be great, just keep at it. One comment, however, why are you using your foot with the 1/4" flange for quilting? The flange is an edge guide, which should almost touch the throat plate. The edge of your fabric runs against the guide. It's not meant to be used where the flange rides on top of fabric, it will pinch it. If you are straight line quilting you should be using a regular sewing foot or a walking foot if you have it. Might have an easier time with one of these feet.
