I found out about this a bit late for myself: I have teapots in process but there's no way they will be finished, never mind photographed, by the upcoming deadline for entry into Lark Books planned 500 Teapots publication. But it might not be too late for you! Check it out here.
The deadline for submission in April 20th; you can submit up to 4 entries.
Lark already has a 500 Teapots book, with which you are probably already familiar. I would so love to be in the new one! But I guess I'll just have to wait for volume 3.
