On his new collection, John Carey teaches Mike Powers' 7 card 21 card trick. At the end, the cards are "spelled", color, suit, number and then true, false or both.
It's great, but he doesn't explain what happens if "diamonds" are chosen, or "thirteen", etc. the words are spelled, then the rest are placed on top. Since there are only 7 cards, need to know what to do when it's a word with more that seven letters. Anyone? John Carey? Thanks. Love the collection

For diamonds, spell diamond. Instead of number, I use value and spell Ace, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King.
