I used something like this on a large sheet and cut it into pieces for a puzzle gift to a website where people left comments. Nowadays even easier to generate nice temporary websites for such things.
The starter kit: a 21×21 board, with three 8×8 finder patterns, two 1×5 timing patterns, and 120 white and 119 black modules.
The Version 2 expansion pack includes a 25×25 board, two 1×4 timing patterns, one 5×5 alignment pattern, 76 white modules and 75 black modules.
And so on.
(I dunno about the desired ratio of individual black and white modules. I gather the general idea is to balance black and white, but does that include or exclude the fixed parts, where black is somewhat more common? Finder pattern is 33∶31 black∶white, alignment pattern is 17∶8, 1×5 timing pattern is 3∶2, 1×4 timing pattern is 2∶2.)
