Thanks chaps :)
Mike, no there won't be any feedback, I'm sure most people barely notice the pictures there, too busy thinking about their books :)
Our waterstones always seems to have done it....i just walked in and asked and the chap said yes without even enquiring what sort of art i wanted to hang, heh. Turns out he's a painter and if someone drops out he takes their place...he's got the main stairs while I'm there for this month.
They don't charge commission and they will take cash if you're lucky enough to have someone buying which is great.
When I spoke to him yesterday he said they were considering charging as a way of maintaining the walls, they are in a pretty bad state, full of holes etc.
So I'm guessing it's at the manager's discretion so definitely worth having a chat with your local store.
It seems like a really nice way to support the local artists.
Anyway I'm still framing them up, bit of a mixed bag really, I'll be glad when they're up and I can take some more pictures :)
