Okay, you are putting your blocks on point. The only difference will be with the edge blocks. Instead of straight lines of blocks up and down, your lines of blocks will be diagonal. They will be sewn together the same way but will need that finishing block on each end to make a straight edge or corner. There is a formula for figuring out how big to make the edge and corner blocks and I am sure that there is a graph someplace. Can you tell us how big your blocks are?
