I've only sent one quilt out. Have FMQ or SID on my regular sewing machine several full size quilts and tons of little ones. Used to HQ, but find arthritis limits my stitching. Love to use a double needle and stitch across the diagonal of 9P for a quick job of quilting. The more FMQ you do, the better you become, so don't give up. And I have a long way to go in the FMQ game!
Most of my quilts are my own designs--love that part as well as picking the fabrics. Expecially love pulling fabrics from different fabric lines as that's what makes my quilt unique.
