Leave the feed dogs up, use a walking foot, and I usually increase my stitch length a little. Start stitching in the middle.
Stitch horizontally down the center, then stitch vertically across the center of the quilt. Every time you start a row of stitches alternate the end you start with. Stitch at the top, next time start stitching at the bottom, when you stitch horizontally, start at the top, next time start at the bottom.
Sew slowly, and don't rush, keep your fabric taught by rolling the sides up to meet the center where you are stitching. I use
bicycle clips to keep the fabric rolled. :thumbup:
