Im ashamed to say I dont use my mulberries all that often.. usually when Im out and 'making an effort' instead of going out dressed like my typical scruffy self! I should use them more though... no wonder my oak rosemary hasnt developed a patina! I tend to use my orla kiely bags most regularly, as they are really tough and hold up to the rain without any problems. Ive just bought a new one from the winter range so that one will probably get used most often for the next couple of months.
