They aren't necessary. We are doing mason jar mugs with lids and straws that way if people don't take them they still have a purpose in our house anyway. found some great deals so they came out to about a dollar per person. That was cheaper than buying or renting glassware for our wedding.
Not necessary. In fact in hindsight I should have skipped mine
I skipped them, but I looked into color changing stadium cups with a cute saying on one side and our wedding date on the other. In the end I decided against them because I figured they would just get thrown away.
It's totally fine to skip! I decided for my wedding we would either do edible favors or no favors at all. We are planning on individual bags of coffee, hot chocolate or tea to match our brunch theme. So far I've only bought the little bags and stickers so it hasn't been that expensive. Maybe I'll change my mind when I have to start buying coffee and things
Favors are totally not a necessity. Most of the time, you end up taking home a lot of them or throwing them out because your guests will forget to take them home. If you want to do favors, though, go with a food -- like cookies or candy. People will love those and you probably won't have too many left over.
So we had 3 favors, but not really. We got married in October, so instead of placecards each couple (and each child) got a little pumpkin with their name attached to it on a card. Each one was $.30 to make, so it was super easy. We also had a photobooth, so people took those photos with them (oftentimes people use this as their favor). Then since we are massive Halloween/Horror fans, we bought masquerade masks in bulk (I think we paid like $40 for like 100 of them). I think we ended up with like 5 extra masks and one extra pumpkin.
