I'm about to cut out the skort and in reading the instructions I'm unsure of how the elastic ends will be hidden. Once you sew the casing top and bottom and have openings on each side seam for feeding, where will you tuck the ends once you attach the elastic 1/8 inch from the side seams? The front waistband is all closed up from sewing it to the back and the back just got closed from attaching the elastic.
