I need some clarification please.  I am creating birth month flower, relationship specific birthday cards. Do I categorize them in  
 
Birthday > Birth Month Flower Specific Birthday Cards > February / Iris or Violet  > Relationship Specific
 
or
 
Birthday > For Family Relation Specific Birthday Cards > Sister > Birth Month Flower Specific
 
The wiki states "Most cards can be placed in 2 categories. This is to increase the cards exposure to card buyers. The exception are name, date/year, relationship specific type cards, etc."
 
Do I place them in both? if not which one do I use?
