Cut the skirt fabric 4 inches long by 15 inches wide. Chalk mark and press both long edges 1/2”.
Sew one edge for the elastic casing. Attach a safety pin to one end of 1/8 inch elastic cut to 4.5 inches long and insert into your casing.
Stitch to secure the elastic.
Open hem and sew center back seam.
I sewed some trim on the front catching the hem at the same time.
And that’s it.
