I didn't make the Kelly bag when it was available, but figured I should give this one a shot just to see if it works. It was a bit unclear how the side gussets were supposed to go together, but I ended up folding a crease down the center of each panel and trimming a bit off the top so the sides would align with the front panel of the purse.
