Next cut four squares for the corners. The squares should measure half the finished block size plus 1/2″. So if you finished block is 6″, your squares should be cut at 3 1/2″ (half of 6 is 3, plus 1/2″ is 3 1/2″).

Thanks Mary. Method 2 is the way I was thinking. so for your 5" block your squares should be 3". half of 5 is 2.5 plus 1/2" = 3" squares.
