Then on the back of my nifty lil invite...lol....it says:
RECEPTION IMMEDIATELY FOLLOWING CEREMONY

I know this probably seems weird without actually seeing the invite, but please give me your honest opinions on the wording. TIA!

*And yeah FI and I have similar last names. Which I think is very cool because my initials are staying the same. Hopefully when I change my lastname I won't forget and write my name because they're so close in spelling for the first couple of letters.
