I wrote this early this morning, but apparently got interrupted and didn't click on "post".
I love the quilt, and had to look long and hard, several times, to finally find a dot that wasn't matching. My goodness, don't sweat the small stuff. LOL
One way to finish the scalloped edges is to face it. Make a strip long enough for one side and wide enough so that when you fold it in half, it will cover all raw edges with about 1 inch to spare. Lay the facing on the right side, raw edges even with the longest raw edge. The corners would be a mitered seam. Sew a quarter inch seam all along the edge, following the scallop. Clip and turn to the back. Hand sew the folded edge to the back so the stitches are not seen from the front.
Happy quilting!
