I really like these books that use up my extra bits of leather. Not just because I save on supplies, but I just think they look really cool with the different colours and stitching. I didn't have enough purple to make a full half cover, so instead I used it as the closing strap in the middle, and to wrap around the front to cover the open pages (because I didn't have enough yellow for that either!).
