What are you most proud of? The ability to modify a pattern to meet her request (elastic and drawstring). What advice would you give someone starting this project? Stich the ends of the elastic to the side seam of the pants then attach the elastic using a serger (if you have it) to the edge of the pants as it helps keep it in place. All you have to do is fold over, stretch, and stitch. Measure out from the front center and make a buttonhole on each side. Attach the drawstring to the front side seams. String the drawstring through the cut buttonholes, fold casing over and stitch down.
