Hi Janey!
What a great idea!
In Tarot, there are 22 Major Arcana cards (although some don't consider The Fool a part of the Majors), also know as Trumps, and the rest of the cards are Minor Arcana, also known as Pips. The Court Cards are Page, Knight, Queen, and King, although some modern decks take liberty with those designations. For example, The Quest calls the Court Cards Mother, Father, Daughter, and Son.
The Minor Arcans consists of 4 suits: Wands, Swords, Pentacles (also known as Disks or Coins), and Cups and goes from Ace up to 10. (Just like a deck of playing cards.)
The Cups suit is usually associated with emotions, feelings, and intuitions, among other things. The number 7 is usually associated with attitudes, dreams, motives--the internal psychological world.
So generally speaking, the 7 of Cups is a card of great potential and creativity. I see this card as almost a "razor's edge" card in the sense that there is a lot of potential with this card, but there's also a possibility for confusion--especially with emotions thrown in!
This is just a very brief syopsis off the cuff. <img src="/images/graemlins/smile.gif" alt="" /> You'd also have to take in consideration the placement of this card in relation to the question asked.
