[MR] heraldic cotehardie

[Alexandria Stratton]

Question for those who know...
I was thinking of doing a heraldic cotehardie. Is there any specific order that the heraldry should go? For instance, if you're doing a pennon, Spike should precede (closest to the pole) the baronial badge, which precedes the canton badge, etc. 
If the front of a cote is a quartered field, what goes where? Or does it matter?
Thanks to all,
