Have a friend buy several dozen roses in the colors the compliments your wedding. Hand each guest a rose as they enter the wedding site. The rose can be tied with a narrow satin ribbon bow for a more formal touch.
M&M candies can be special ordered. Order colors that match your wedding scheme. You can also have them imprinted with the first names of the bride and groom. Package a 1/4 cup of M&Ms in a clear cellophane bag tied with a ribbon. Hand each guest a package or place the packages in baskets at the exits.
Buy tapered cream colored candles, one for each guest. Tie each with a narrow satin ribbon tied in a bow. Have business sized cards printed that say “Josh and Sue share their love” or something similar, with the date of the wedding. Punch a hole in each card and thread onto the end of a ribbon then make a small knot to keep it from sliding out.
