There are 740 inch and a half (finished size) squares with no repeats as far as I can tell. I was 8 squares short so I picked out 8 black to light grey squares and added them at the bottom corner.
The mind boggling thing is that I have 740 different batiks in the stash. Well, that's not true. I didn't use any of the cream based neutrals, so they are not in the count.
Ahem...we'll just not think about how many of those I have. I am actually considering making another one like this but doing it as a colorwash.
