i understand what you saying about how the numbers read but where i have #1 you have #1 too and where i have #5 you have #5.
are numbers are in the exact same triangle sections except my piece isn't printing upside down.
when i preview my blocks/triangles my pieces are all a mess and on top of each other.
i have to pull them all apart and move then around, i've never had my pieces nicely placed like yours.
