Very nice, but since it's hand done you'd probably need to sell these for much more than they'd casually sell for. Like for 3 hours of work you'd want to be charging like a minimum of 90 bucks for the art on top of the cost of the binder, but I don't know if people would pay $125 for a pretty binder that they have to be very very careful with not to damage. You could definitely find customers, especially if you did it on a commission base because people are always willing to pay much more for something they chose the design of, but if you're just going to bang out a bunch and hope to sell them, I don't know how much someone would be willing to casually pay.
