The only thing to watch is that all three templates show a test square of 1.5 inches so that the church pieces match, as long as your test squares on the different templates are the same size, you should get a consistent block that is enlarged or reduced by the scale you chose.

Here is a table that shows how to enlarge and reduce blocks to different sizes, works great for PP as long as all your templates are enlarged or reduced by the same percentage..I sound like a broken record, :mrgreen:
