Funny how doing something a new way changes the way I feel about sewing.
An online tutorial for a gypsy skirt, the current name for tiered skirts, had a better ratio than the ones in my vintage sewing books. I love it : hip measurement +4 inches, than add 20 inches for each successive tier. All tiers are 9 inches wide.
It was so easy and satisfying that I decided not to make a casing for the elastic and thread it through, but to butt the edges of the elastic together, fold the fabric over it, and stitch.
Oh yes! Gone are the days of tugging elastic through casings.
