@foone Oh wow, I found 11x17" with 8 sq/inch at my local art shop and got it to make minecraft plans on (And then have only used it to make Fire Emblem shipping grids)
However, if you just need lots of squares, it is 88x136 squares, which isn't THAT far off the 96x132 squares you listed. Would that work for you? I can look up the brand and stuff if you want, I've got it right over there.
