This is the messenger bag I've been working on, which is now for sale in my Firefly Farm shop. It's made with the vintage fabric I mentioned here.
The inside has a couple roomy pockets and is lined with this mini floral fabric (not a great shot, sorry).
The flap has a big old button and a velcro closure.
This was much more fun to make than my last bag; I think I'll stick to my own simple patterns.
