Hmmm, no clue! Could it be your machine? I'm a better piecer, too. Tried fmq for the first time a few days ago, was AWFUL. I threw the sample in the rabbit cage to be chewed and peed on. Hand appliquéd for the rest of the weekend. I know it takes practice, and I got great advice and support from this board. Your problem surely has an easier and more immediate remedy. The board will come through! Btw, like your quilt, pretty!
