This is the first time I've heard of someone having a carnival theme, but I think it's a brilliant idea! To plan the perfect wedding, you need to ensure you have a budget in mind, as this will alter the number of choices available to you. Start by getting your guest numbers set in stone, so you know how much money you will have left for decorations and activities. I strongly advise hiring a wedding planner as they can find the most suitable venues and stylists for you so that you don't feel so overwhelmed. Hire a caterer who provides carnival-style food such as hot dogs, pretzels, burgers and doughnuts. You could even create a sweet cart and have lots of fairylights everywhere for when the sun goes down. Bright colours would be perfect for your theme. Think of reds, blues and whites. Have your waiters walking around on stilts in fun outfits, and look for themed stationery to tie the whole day together. The most important thing is to stay calm, take it one step at a time and don't feel the need to do everything at once. Begin with your venue and guest list, and once that's sorted everything else will fall into place.
