I like back packs but never use one as surely they are easily opened by someone standing behind you with evil intent? Leather is lovely but too heavy for me. I have lots of bags, none of them expensive, all of them shoulder bags and some from charity shops, but my current favourite is a Mantaray one from Debenhams. It is made of peach coloured fabric with a flower pattern and is just the right size, ie not too big and not too small. I love that feeling when you buy a new bag and transfer all your stuff from the old one to the new one. I had a clear out during lockdown and got rid of quite a few to the charity shop. I have to be minimalist beause DH is definitely maximalist - never chucks out a thing.
