LOL language..........sometimes it's difficult to explain. I use 1 template for all the pieces to be cut with that template. So there are 6 subunits of one block, for each unit you need 2 pieces, 1 up and 1 down (or mirrored).
This doesn't count always though, depends on the design of the block. Sometimes you don't have to mirror the pieces. Do you still get it??
