|May Book Blog: Serge With Confidence by Nancy Zieman|
Turn up the bottom hem to the wrong side so that the serged edge just overlaps the lower edge of the shadow stitching(you should be able to see it through the fabric).
Press and take to the sewing machine. Topstitch on the right side just beside the shadow stitch line in thread color that matches your project. The stitching will catch the hem on the wrong side.
Now since your bonnet piece is curved all the way around, you will need to ease in the hem. Run two gathering threads at least 4.5 inches long 5/8 inch and 1/4 inch from the curved edge.
Pull the threads around the curve gathering slightly so you can fold the edge under to slightly overlap the shadow stitching line.
Press. Straight stitch from the front around the outer edge, just as you did across the hem edge. This will create your casing. (You will have some gathering on the wrong side of the fabric, but since the bonnet is drawn up with a ribbon, this is fine.)
Run a ribbon through the casing using a safety pin.
Pull up the bonnet to fit. To secure the bonnet shape, stitch through all layers (including ribbon) at the edge of shadow stitching beyond the casing opening.
Tie knots in the end of each ribbon.
