I've got the first three chapters of Grassblades collected in a single volume, and am hoping to keep doing that with the rest of the chapters - just gotta space it out a bit and raise the funds; printing is expensive. I've also got an artbook full of tea-based witches. <3 The Grassblades volume is 100 pages, the artbook 50 pages, and they're 8.5x11 inches, or a standard A4 size, in full colour on 130 gram silk paper.
I sell them at cons, and also have them up in my tictail store.
(photos are darker than the IRL copies because my phone is terrible)
I printed them with a local Swedish printer, which meant that the printing cost per book was higher, but I didn't have to pay shipping at all (lucky me; these buggers are heavy) as I could just go to the print shop and pick them up in person. Also, they're reliable and always turn out good work, and there's never any trouble when it comes to proof-copies or correcting errors.
I've been part of an anthology that was printed via Ka-Blam, but I wasn't in charge of that, so I'm afraid I can't give you a personal review of it. IIRC, it worked just fine, though.
