The inside of the Oberon journal cover is just the underside of the ~ 1/8" thick leather.
Lilly -- from your pics, it looks like you want to include the cover of the journal, inside the leather outer shell? Wonder how you would neatly disconnect all the journal pages.
Anyway --- if you want the journal cover included for the stiffening -- Somebody else took the $29 Amazon leather-with-hinges cover and just stuffed it into the book edge pockets on the Oberon cover. No extra effort then, to glue the hinge piece in. And since you have to buy both bits ANYWAY - the Oberon journal cover (which includes a hardbound unlined journal) AND the Amazon hinged-cover -- why not buy them and try fitting the one onto the other, without any other mods?
If you don't like the fit, you can *then* send it onto artsci for further modification. But if you *do* like it, it's already done. Plus you can tell us about it!
