A game table. This helped keep things organized for everybody. We made it a point to use a different table cloth so it was easily identified and put balloons there as added 'pop'.
On the far right of the table we had a basket and lots of newborn diapers spread out in front of it. We had a few sharpies sitting nearby as well and encouraged people to write notes on the diapers for the mom and dad to read when they were changing them. Some of the notes said "You know you love me!", "This, too, shall pass." and "You are the best parents ever!"
Another game we had involved a huge plastic baby bottle filled with pink sixlets. It was a "Guess how many are in here" game. I zoomed in from the picture above so you could see it a bit better.
The three bottles behind the sixlet game were our "Grand Prizes". My husband painted them to be gold, silver and bronze. As everyone entered, they were given a small pink clothes pin to wear. During the entire shower they were not allowed to say the word "baby". If they did, and someone caught them, they would have to surrender one of their pins. At the end of the shower, the three people with the most pins each got one of these bottles. They were filled to the top with different chocolate and candies.
We turned the mantle of the fire place into the gift table. The flower pom-poms on either side were made by yours truly (I have a tutorial up for those in my Crafts section!), and we added some twirled streamers to give it an extra flare.
Here are the pom-poms suspended from the ceiling above where the games were played.
There were some children that we knew would be at the shower, so we blew up some extra balloons and threw them around so the kids could play with them.
By the snack table we took some of the baby clothes we bought for the mother-to-be and used the pink clothes pins to hang them from the window blinds. It made them much more attractive and added to the decoration wonderfully!
Although it is slightly hard to see, between the two posts we tied a thick piece of yarn and hung the matching hats to the outfits on. As an added precaution, we hung the streamer low so people would be less likely to walk into it. We didn't have any issues.
