I brought tons of custom items, but nothing that could really be classified as "decor"... I brought a seating chart (in a large picture frame), table numbers/kissing menus & stands, drinking straws with flags, custom guestbook sign, some "diamonds" to scatter around my cake table, guestbok table, and seating chart table, custom cake topper, and custom napkins. I also made detailed programs for the ceremony. I found that using my own table numbers/kissing signs was enough "decor" for the tables in addition to the decor that Carnival alread had on the tables.
