So I actually finished this a couple weeks ago but wasn't pleased with the result. I finally had the time to revisit it and make it work. The first round I had an extra leather flap around the top because I was originally going to use straps to close the bag, the result was an incomplete closure and wonky lid. I removed that flap and just attached the zipper to the lid and I am now 100% pleased with my result!
Here is a link to my original post if you would like to see my first version.
