On my last custom job for a client, the design I used had a "tuck strip." That's what I'm going to call it because I don't know if that type of closure has a formal name.
It occurred to me that this type of closure would work on the Soap Tote. So I gave the traditional model of soap tote a makeover, tinkering with other elements as well. Now it has even less sewing but the same basic design. More efficient for me to make, and perhaps a better and neater way to close it up, since the more sewing, the more potential to sew crooked or have my sewing machine decide to be all sensitive and oversew or some such thing.
I work with recycled billboard vinyl advertising tarps. Those products are for sale available at http://www.vinally.ca/ I also sell at http://www.etsy.com/shop/VinAlly
