On the Jay Ham article where he makes a spinnaker pack, before he finishes up the pack the side panels are sewn to the back panel. Would it also work if you just flipped the side panels around and put them on the front panel, and then threw it all together? Sorry if this isn't very clear, hopefully someone can understand me :P
