I have a ton of 100-word microfiction, and theoretically I could take the best hundred of them and put them in book form. It’d be about the size of a chapbook, so it’d be a $2.99/$4.99 project. The problem is, they’re microfiction. Don’t know how many people would want to buy that.
I could value-add it by including illustrations. The problem there, though, is that the art costs go up significantly when we’re talking about one hundred pieces. Even if I spent no more than five bucks a pop on the art (which would get me, I dunno, stick figures or something), that’s still five hundred bucks which I won’t see recouped any time soon. And I wouldn’t want five-buck-art, anyway.
