Free-Motion Quilting...Loops?

While I was working on the last quilt, I ran into problems with these loops showing up on the back side of the quilt. It seemed if I kept my stitches neat and smallish, the effect would be minimized, but I grew frustrated with their presence, and my inability to eliminate them. What to do?



Last Thursday night, I was flipping through a book by Katie Pasquini Masopust and found a side-bar note about the subject. She suggests threading the needle with the presser foot in the up position, otherwise you'll find these loops on the underside of your quilt. In all the possible things I could think of that I might be doing wrong, this did not occur to me. And to think, I found this solution very much on accident.

So, I have hope that the problem will be resolved with the next quilt.
