Art versus craft

Sometimes I wonder if I've gone on this path of making journals to avoid "real art." Are these books that I create art or craft ... or perhaps both? When does craft become art? (This question assumes there is a hierarchy.)

The book structure and binding are simplistic ... I craft them.

The pages are arty when embellished with paint and/or collage. Collaging and piecing and quilting the cover is arty. So does that make them mixed media art?

"Funkiness" is art, yes? The scrappy journals are funky, not scrapbooks with perfectly designed layouts.

Scrapbooking is craft, yes? When does scrapbooking become art?

What, exactly, is art?
