If you look back at the green and black bag, you might notice one difference between it and this bag but there is another one as well. Of course the brown one does not have the button flap. I left it off because I decided that I wanted pockets in the front and the back, so I made 2 fronts instead of a front and a back and decided it would be better without a flap.
Question- do you prefer to have a closure on your bag or not? There just aren't many pick pockets in rural Georgia so I don't need a closure and I think magnetic clasps are expensive. The button flap is a nice decoration but I only want to sew a button on once (if it were to fall off, I'd rather ditch the bag and sew a whole new one) and the button slows me down.
