I was looking through Get Married Fall 2011 magazine and ran across this really cute idea. Make a cone out of any decorative paper that matches your reception colors add a decorative tag that reads "Thanks a Bunch" and fill with flowers, candy, or pretty much anything you like. We've done similar cones tied with ribbon to chairs at the ceremony. These were filled with petals to throw as the bride and groom walked down the aisle after the ceremony. It's a pretty cool idea.
We have also offered guests water bottles decorated with the bride and groom's logo. These are great for handing out before an outdoor ceremony. Guests love it!
