It definitely isn't perfect but It's done.

I had to add an external pocket for keys because the bag can't be carried over the shoulder while it's open. The nature of 'uncomfortably open' or 'emphatically shut' isn't something I was aiming for. Might end up being a bit irritated and wishing I'd put in a zip!
Also it now looks more like a proper handbag. I was quite fond of the fluffy sack look it had before.
The handles should be bomb proof though.
It's reloaded so it's time for a road test.
