You don't actually have to put a dime or a pencil on your head. Just look at your head and kinda make a section that size. I didn't do bricklaying patterns. But go out side and look at a brick wall. the bricks have a pattern. Say that these 4 xs equal one brick or one section ok?
XXXX XXXX XXXX XXXX XXXX XXXX
XXXX XXXX XXXX XXXX XXXX
where there is gap between two bricks in one line....in the next it is the center of a brick in the next. You can do this vertically and horizontally so that there are no long straight parts on your head.
