Leather details in interiors

I absolutely love leather. I like it when it's new, when it's aged, tanned, I the like way the patina evolves over time with wear. So I've complied a small selection of ideas, some very Scandinavian in style, about how you can use leather products, or little details in your home or office, in combination with wood, another natural material which ages beautifully. Some of these below are very easy DIY ideas, whereas other, you just have to appreciate a well-designed products and bow to the designer.
