I know I've read a thread or two on this already, but with the search function down I haven't been able to locate any at the moment. I've got one bag in particular that has a fairly wide, single strap but it's in a glazed leather which makes it quite slippery so it keeps sliding off my shoulder. I love the bag, but if I can't get it to say on I might have to part with it. Can anyone offer me some suggestions?
