Good idea on the waterproofing. I think I'll give it a try.
As for the pocket, well, I'm a sewer. Lousy cook, but I can sew anything, so the whole idea just intrigues me. I was actually going to try to make it on the whole bottom half of the bag and it would just curve. Still in the thinking stage. I've even considered trying to make a bag, but my machine is not heavy duty. I'd love to someday have one of those old heavy ones like our moms used to have! ramble ramble ramble.
