Reception Details to Remember

Hi! I am struggling with thinking of all the reception details that we need. I'm thinking of little things like decor - what do we need? I know we will have a welcome sign and assigned table sign, we plan on having a bible as a guest book for people to highlight their favorite verses and write notes. I have candlesticks and candles for the center of my guest tables. We have a photo booth, we have a dessert table with a sign. And I'm doing a generations of love table. What else is needed? Should we put candles on all of the tables that we're using? What are the little things that i'm missing?!
