You're never too old to learn something new. I use my embroidery machine  to piece quilts as well, and found an easier way to help with the bulk. While stitching the excess is folded under the free arm ( it shifted while taking the pic, it's actually more under the free arm than this), and I only have to give it a little tug as I am sewing. Just be sure that it is smooth with no puckers as you stitch.
