I’ve been designing bookplates for Tansy Rayner Roberts, for her (successful!) Castle Charming kickstarter (I previously posted about the enamel pin design for that).
Here is the first glimpse of the bookplates back from the printer (Tansy arranged all that end of it — I do particularly enjoy the moment where someone else takes art away and brings it back as a shining object).

It’s pen and ink with ink washes.

And here are a few of the sketches from which it began:

Books are fascinating as design elements. They seem so potentially decorative and yet they’re very… boxy, and make you make style decisions around e.g. perspective, and how shabby to make them in order to get some texture going.
Some of my favourite books covers are early 20thC school prize book editions. Mostly because of their spines! But the other sides are marvellously textured (and the insides are gorgeously mottled — blank pages in Mr Dalton and Janet have provided many of the textures I use with digital colour).
