I'm glad that I'm not the only one in this boat. I'm not a jilted maid of honor, just a frazzled one!
I'm hosting a wedding shower next Sunday for my best friend, and am expecting about 10-15 people. Since I have more spare time than spare money, I'm making little felt wedding cakes for my guests based on this pattern:http://www.craftster.org/forum/index.php?topic=26836.0
I have a few larger gifts to use for the games, but I'll probably borrow the chocolate-in-tulle idea for other small items!
For decorations, I hope to make a larger, 3-tiered version of the felt cake (and probably give that to the bride), and add some balloons around the house.
Great suggestions from everyone, thank you--they helped me out, also!
