Yay! That was my last baby's shower theme, too! It is so fun! Here are some pics from my shower:
(You could do polka dots on choc covered strawberries!
You could do pink tablecloths with cut out black construction paper circles taped on them. Cupcakes with candy ladybugs on top. A lady bug cake. (red cake with black dots. Google for fun ideas!) I hope you guys have fun!!
