The Aivilo Curvy Trio features patterns for three great bags at one low price. All are simple to sew, and the clever button hole on the flap is very simply made by leaving part of the flap's seam unsewn during construction; no buttonhole feet or knowledge required. You can also use a loop of elastic to hold your button in place instead of making a button hole. It can be made from several different fabric configurations to produce a monotone, checkerboard, or patchwork style.
