We kept things simple. I hung two clothes lines with some basic onesies, alternating white with some colorful ones. Then we hung some colorful tissue pom poms. I made these using the Martha Stewart tutorial found here. So simple. So easy and inexpensive. Walmart has packages of tissue paper for just $1.
For food we had cake, but then we also had animal crackers, malt balls, pretzels, honey nut cheerios, and mints.
It was fun. Most importantly, I think the mother and father-to-be felt showered with love!
