I've just completed this bag using vinyl and cotton. My inspiration was the Rose Fabric Tote Bag, and I made a few changes
I added outer straps similar to the Charlotte City Tote Bag by Swoon, and vinyl to the top, as well as to the bottom of the bag, and down the center..
Instead of a flap, I made a recessed zipper. This was my first attempt with putting one in. I didn't do it as per the instructions, but it turned out well . There is also a large inside zipper pocket and two large open pockets. I added peltex to the bottom of the bag, plus an overlay of interfacing.
I'll take a picture later today of the inside of the bag and the recessed zipper so you can see what they look like.
