And this os one of the only time you will see me pin on a block, the last thing you want is all these pieces getting mixed up, trying to sort them is a pain, ask me how I know.......
Overlay then so that they will be approx where they would be if they were sewn and stick a pin or two depending on how big your block is, usually one will do it,
And we are done our first block, this is as far as they go until you go to put the whole top together,
