This very successful experiment was a variation on the easy elastic-waist skirt for a little girl. I started with an extra large cotton tee shirt from the thrift store, cut it across the body just below the sleeves, then made an elastic casing at the waist. Softer, drapier, and even easier than a skirt from a rectangle of woven fabric, because there's no hemming necessary, and no finishing--the jersey won't ravel.
Which leaves you time to do the fun part: sew pink beads around the bottom. Even that goes quickly, and you can do the whole skirt during a half-hour piano lesson.
I love that it looks like those candy buttons, or a stylish wedding cake with the little rounded dots.
