Have you tried using contact paper?
1 You draw the design that you want on the paper side of the contact paper. You can cut it in strips, squares, circles or large pieces.
2. Slowly take off the backing and gradually adhere it to the quilt. Then using the darning foot with the feet down, sew through the written pattern into the quilt.
3. When you are done, pull off the paper with the written design and you will see that you have sewn the design onto the quilt. Pull off the paper, using fingers or tweezers
4. This method gets you used to moving the material without jerking it around. I did it a couple times and then did FMQ with no paper, just using my hands and moving material. The gloves rubber-tips called Fingerlings help. It also helps to sing or hum to keep from being so intense that your grind or bite your lip.
Have fun.
