I Have used the CAMBRIDGE system, with my machine to tack quilts .It is a paper pattern in shapes like hearts, diamonds etc. with hole for sewing. just pin to your quilt and do a tack stitch in each hole, then cut the thread tails off and you are done, Can reuse the pattern over and over. makes a neat look.. dont remember where I got it , but think it was a quilt show in FL.
