Plan early, and factor these expenses into your budget. Your attendants are among the friends and family who mean the most to you, and you'll want everyone to feel great about your wedding day.

Keep track of your deposits and spending, who paid for what, and how they paid for it. This will help you avoid anyone going over budget and help you to stay within your means.
