Good information here. Somewhere in the many quilting books I have read they talk about "stitching in the ditch" and the article said to NEVER stitch directly in the ditch but a thread or two away from where the two pieces of fabric are joined. The reason for this is because if you stitch DIRECTLY over the stitching where the fabrics are joined you will weaken the threads. Makes good sense. I hope the way I have written this makes sense. ;-)) I love to STID when I am not sure of what other kind of quilting pattern to use. A good way also to make a particular piece stand out.
