The day of the marriage is frequently more stressed for the bride than any of the planning process has been. Start your morning off with a calming bubble bath or a massage at the spa.
Do it alone if you want some non-public time ( since you'll be trapped by folk ogling and trying for your attention for what's left of the day ), or if you are scared and need to talk, invite the bridesmaids along for some pre-wedding cosseting. Do not forget to give your chum a gift for helping you thru any marriage day glitches. Arrive at the church with masses of time to spare. Remember, you MIGHT tear up a bit, so have masses of tissues handy as to not smear that beautiful make-up.
Spend the last few mins before the marriage starts with your bridesmaids.
It's cool to have creative control over the music, and it gives you and your future better half a project you can work on together. A large amount of rental halls will have kit available for you to play your CDs, but you may also hire this equipment fairly cost effectively. But still use the paper invites for your folks, since this is the more standard route.
