What to do About Little Books?

My little pocket books are @ 3" x 4" and they fit quite comfortably in pant and jacket pockets. When I first started making these visual ditties as alternatives to traditional holiday cards, I had no idea if people would like them or even buy them, but they did. They seem to work best with simple accordion folds, front/back text, and covers affixed to the ends of the fold.

My creative challenge with these books  is to stay inspired--to keep coming up with fresh ideas for covers, folios, folds, bindings, and text. How they may be used for other purposes. Come to think of it, since they are a cross between greeting cards and little books, I could call them Nef's Bards--but then I'd have to use poems for text to make that work and a few visuals, of course.

I think I just started a new project.
