Cover up?

Yesterday I bought a new cover for my iPad as my old navy blue leather one was starting to look a bit worn and tatty. I never realised how difficult a job it would be to replace it... There are just so many variations out there now. I knew mine wasn't an iPad mini, so I could discount those covers pretty quickly, nor was it an iPad Air but the shop assistant assured me the covers for that and the iPad versions 2, 3 and 4 were interchangeable. Fortunately, I didn't believe him as when I came to measure the two against each other, they aren't! Anyway, this is what I settled on - I rather like it!
