Decorate the Bride - Get at least a weeks worth of news papers, lot of tape, and scissors. Break the guests into groups. The groups are "Skirt and train" "Bouquet" "veil and jewelry" and "bodice and shoes" groups. Have the bride-to-be stand in the middle of the room and have the groups go to work making a newspaper wedding dress. Make sure to take pictures after!
Collect the Clothespins - Pin a clothespin on everyone when they arrive at the door. During the shower if anyone crosses their legs and someone notices, the noticing person can take all of their clothespins. the person with the most clothespins at the end of the shower wins a prize. You can pick different things besides leg crossing, saying someone's name, saying the word "wedding" etc.
Know the Groom - Print out THIS sheet. Call the Groom ahead of time and ask him these questions. Tell the guests that the bride will have to guess his answers the questions. Have everyone write down how many she will get right. The guests who guesses right (or closest) get a prize.
Wedding Concentration - A fun game for all showers.
Wedding Shower Bingo - Print out enough of THESE bingo cards for each player (best if on cardstock). Before opening the gifts have the guests fill in their cards with the gifts they think the bride will receive. The free spot in the middle is where they put the gift that they brought. Have them cross off a square when the bride opens that gift. Whoever gets five in a row first gets BINGO
Points Poem - Give everyone a paper and pencil. Stand in the middle of the group and read them this poem. Whoever has the most points at the end wins. Some points may be disputable. Give points you think are rightly deserved :)
