In order to break the alignment of vertical points to be in same straight line ,queen closer is placed next to quoin header in each alternate coarse.

Header coarse must not start from queen closer as it is lible 

to get displaced off.

A lap of 1/4th of brick is available for each stretcher over the header in the coarse below it.

For the walls having the thickness in the odd multiples of half brick thick.Each coarse shows stretcher on one face and header on other face.
2> Flemish  bond
If the arrangement of bonding that consist  of header  and stretcher in each coarse.

Header in  each alternate coarse is centered over the  stretcher in the coarse below it.
 Every alternate coarse in this bonding start with an header.
In order to break the alignment of vertical joints to being same straight line,queen closer in place next to quoin header.
For walls having the thickness greater than 1.5 brick thick ,english bond is found to be stronger than flemish bond.however flemish bond more asthetic apperance than english bond.
Flemish bond is found to be more economical than English bond,as no of half bats are used in this case,which reduces its wastage .however mortar required in this case is comparatively more due to more number of joints.
Skilled labour is required for the Execution of Flemish bond .As vertical joints in the same straight line to be avoided.
