My batting is thin cotton and the backing is a medium weight cotton twill in aqua which worked well with the colours in this quilt top. I used a rainbow thread and a wavy decorative stitch to do the rows of quilting along both edges of the horizontal seams. I have learned to go back and forth instead of always starting on the same side to keep the quilt balanced as it is easy to get things shifting in the direction of your lines of stitching.
I used a bright and fun striped fabric for the binding with a much smaller version of the same wavy decorative stitch!! Therese
