We didn’t really discuss that but if people are interested in other sizes or formats outside of the letter size (11x17 when open) we usually publish definitely let Brad or myself know. Remember too, oversize and/or heavy things start getting prohibitively expensive to ship particularly outside of the US and most people, myself included, don’t like spending more on mailing than the product itself. We do take that into consideration every year.
Cheers,
