If the machine is truly skipping stitches I think it is your needle, you need a Quilting or Top Stitch Schmetz 12 or 14 needle for quilting. Sometimes the batting scrim can cause stitch problems as well. Having your dealer check out both the BSR and your machine is the best place to start. It helps to have the same weight thread in both the top and bottom as well. Good luck, I feel your frustration.
