Mostly money, some people make gift lists.
We got a mixture of money and household items.
I have never been to a non Jewish wedding but this is a typical Jewish wedding.
approx 3/4 pm: Reception, might be finger food served at this point. Men and women seperate. Towards the end of this groom comes to bride accompanied by both fathers, the father blesses the bride, maybe some other stuff is said. The groom places a veil on the bride.
Groom goes to chuppa (with either both fathers or mother and father accompanying him)
Then bride with mothers or parents follows and wedding ceremony takes place.
groom places ring upon brides finger, seven blessings are recited, a glass is smashed. In chabad circles there are no PDAs so bride and groom won't kiss or hold hand (in other orthodox weddings they won't kiss but might hold hands)
Remember the bride and groom haven't touched until this point.
Then the bride and groom go to a yichud (alone) room. They get about 20 minutes or so when non one is allowed to come in. Being alone (with the potential to have sex although modern wedding dresses and make up and hairdos prob make that inpractical today) completes the wedding ceremony and the couple are now considered married.
Then there are wedding photos and family photos.
Meanwhile other guests just mill around, in some weddings finger food is served at this point rather then earlier.
Then there is dinner and dancing.
Very religious weddings - male side and femile side, entirely seperate seating and dancing.
M.O weddings - mixed seating, seperate dancing.
Jewish traditional - mixed seating, seperate dancing to begin with, mixed dancing after meal. (rabbis all leave at this point)
