Hello everyone! I'm working on my second quilt, and am having some problems with some of my stitches. This is my first time trying free motion quilting, and I'm using a Gracie quilting frame. Most of my stitches are fine, and everything looks good from the front. However, sometimes the stitches on the back are too loose. I've noticed this especially after I load a new bobbin. Do you think this is caused by too much/little tension, speed, over loading the bobbin, etc? Also, do you have any suggestions for correcting it. I plan on removing these stitches and re-Quilting those sections after I have finished. Thanks for all of your input!
