i spent months preparing my wedding, it was almost completley diy. the night before we set up the reception space, made bouquets and set up flowers, and made all of the food. i felt very prepared.
everything went over really well, except i put the song i walked down the aisle to on a cd and the stereo we had did not take cd s! thank goodness for smart phones, my cousin downloaded the song and had an aux cord so it worked out.
that is wonderful to have a personal touch for your wedding. it makes it all the more special.
