M.N.
What time of day are you serving food? The first thing I though of was "Dirt for Dessert" - made with crushed oreos, vanilla pudding and gummy worms in a mini flower pot. Appetizers could either be a green (food coloring)cheese or pate on crackers. You might do fine with a sheet cake, with a garden fence and flowers on it. I would look at Better Homes & Gardens or Real Simple web pages for ideas. Remember KISS: Keep It Simple Sweety! Enjoy the day and good luck. Let me know if I can help with either of my mom-owned businesses: photo memory books through Creative Memories at www.mycmsite.com/mindynemoff or decorative and affordable expressions for your home or business (including window signage) at http://MindyN.uppercaseliving.net/
