In the past I got cards back telling me if it was an invitation it could not also be in another category.  OK - I'll work with that.  But now -  
This one seems unreasonable to me.  Just got a card back saying invitations can only be in one invitation category.  WHY??  I am trying hard to get on board with picking categories and making cards that fit specifically, but this rule just seems like you are not thinking like shoppers really think
 
Here's my cards: 518823
 
I wanted it in costume party and pumpkin carving party invitation. Frankly I doubt you sell very many of either one and those categories are not over-flowing with too many designs.  My verse specifically fits both.  
 
I have several others that fit neatly into more than one invitation category.  Sometimes I don't think the rule makers have thought this through the way regular people shop ... or maybe I'm irregular  .
As a shopper in either of these categories I would be happy to find my card.

Hi Amy,
 
I agree with you about your Labrador cards.  Those three colors of labs are very distinct and should not be considered the same as changing the hue on a flower and calling it a different card.  You should indeed be able to use each of those designs 3 times in different categories with different words on the inside.
 
I hope the support folks agree with you and make your customers happy.

Thanks Doreen and Linda (Black Lab lover proving my point   - personally I love all 3).
 
I have been going with the flow on this topic so far, but decided to bring it up while I was asking about rules since I know it will come up for me again.
 
Funny story to make my point - I use to make felt Labrador ornaments and at one time I couldn't get the gold-ish color I used for my yellow dogs, so I bought a tan-ish felt instead.  WELL - that got people all worked up so that they started requesting the "dark yellow Lab' vs the 'light yellow Lab" and if I ran out of one some people wouldn't buy the other. - LOL.  They were silly felt ornaments for goodness sakes  .  I did my best to please everyone of course.

Amy
Thanks for posting an interesting question
Rules , while well  intended, do not always work  
While i understand  GCU needs to be highly specific so cards stand out in searches and draw traffic
 
In the end GCU & artist want to draw buyers who found what they wanted  and bought a card.
         and not just searchers who got what they asked for in a search,  
                but not what they needed to motivate them to buy.
 
Through experience you learned  and  
your problem is a perfect example  of a rule thats need to be broken and adjusted at times
You learned where real sales interest is and what buyers needed and wanted to buy and not just what they asked for  in a search.
 
I accept that GCU MUST be highly specific to get searchers in,  
        
  But once visitors came in from a  simple hightly specific search buyers need to see other variations of cards designs to motivate them to act.    
 
Once buyers get here and see the qualified highly specific cards
there needs to be a way to see a broader wider range of cards with  similiar natures
 even if an exception to the rules
 
I have previously been in your place several times  and cursed GCU in anger  
until i finally realized their need to be specific for searches and realized it was a good rule
but there are many valid exceptions and many times GCU & artist are not even aware of them.
 
Hopefully GCU will make an exeption in your case and other valid cases  
Because in the end buyers buy what they want and not always what they asked for.
 
If GCU shows visitors only what they asked for  and not what they wanted, it may fail to motivate them to buy and we all lose
