Hi Samiec1,

It's very common to place pictures of family members in frames by the sign-in table at the entrance of your aisle. Another thing that is special is to find one of his favorite things - kind of tree, hobby, animal - and do something with that. For example, let's say that he loved maple trees. You could place a wreath of maple leaves on the seat he would have been in, in rememberance of him. You could also blow a conch shell in his memory. That's more of a Hawaiian tradition, but can still apply. It's meant to summon spirits of the couple's loved ones to gather for the ceremony. You could include the meaning in the program so people know the significance.

Also as far as your question about the decor - you could fill short square vases with sand, sapphire sea glass, shells etc with a candle in the middle. Then with other sized square vases encorporate your white roses. To bring in the silver - in place of napkin holders use a silver ribbon to tie around the napkin, then tuck a starfish under the ribbon to finish it off. You can get these items at most fabric/specialty stories like Michaels or Joanne Fabrics.

Hope this helps!
