Here are two I just finished. I'll probably xpost them on the DIY board.
Escort cards (just finished the design!) - will be color coded by entree. The quatrefoil pattern is one that was on my save the dates and the envelope liner on my invitations:
Card box - my centerpieces are all various lanterns - this one i got at a warehouse sale for a few bucks because the front and side glass was missing. I cut a piece of foam core for the back (so cards can go in from the side), added the ribbon to the top, the love scrapbook stickers, and then used a chalk marker for "cards" and our initials in the heart on the side.
