I liked the bag and decided I needed one too.....a bit smaller, a brighter interior and a different shaped flap with a vintage button closure....and the bag above is the result.
We have a trip to Ecuador coming up in December and David needed something to comfortably carry around "The Birds of Ecuador", a colossal tome which will be his bible while we're there! And the book itself needed a jacket to keep it clean and protected. I had the perfect fabric for it.
The bag needed somthing sturdy and a navy twill that had been acquired at an auction sale was the perfect choice. A divided pocket on the back is the perfect place to keep a notebook and pen handy while the interior is sized to comfortably hold the field guide.
