Gallery 3 - Weddings

I particularly enjoy weddings. I like to think that the happy couple, with a similar sense of humour, will laugh together at the details and perhaps little secret I uncover. One of these shows a couple who loved puzzles. I had fun in weaving in a few little mysteries for them to uncover the meaning of. What are the answers to the questions? Why would that be significant? What's the meaning behind the number 13 squared?
