In terms of simplicity this was... simple. Just straight seams. All square. But with over 800 stitches using upholstery leather it ended up being tedious. I had to use small needles and small nylon thread which tangled easily. I use double needles so the thread "floats" in the eyes and it kept slipping out and I'd have to re-thread the eye. But I'm happy with my first attempt at a bag. This is small which is what I wanted. My Kindle or a paperback fits just right. 4 pockets inside and two of them I made with my fly wallet and tippet spools in mind.
