As I've told you before, I made the bag from pieces of leather which have been used as colour samples for furniture. It's fairly thick leather and I love the colour.
I made the shoulder straps from the belts which used to hold the couch cushions in place in grandmother's old house (they attached the back rests to the wall and were going to be left behind when she moved). I'm curious to see how well they'll hold up because this leather is old and feels really dry. I left the original end with its large oval brass grommet on one of them, as you can see in these pictures.
The shape of the bag is very simple. Basically just a big sack with the bottom corners squared off, a zipper at the top and a shoulder strap which attaches to the side seam part of the way down.
And of course it's lined and has a zippered pocket in the lining.
In case you're interested, this is the pattern, with the measurements.
It's a bit bigger than my previous bag but it 'hangs' nicely. I think this bag and I are going to get along just fine.
