My sister in laws want to have a get-together for Valentine’s Day, they’ll provide the drinks and I’ll be hosting. Other than balloons and karaoke I’m out of ideas for homemade decorations and snacks. 
Any help is appreciated, as my internet searches have been unhelpful.
Good question. I guess a girls night out type of vibe. The guests are very do everything at the last minute, so it probably will be like that. I am not, so I prefer to have snacks etc on hand. Hopefully the bodegas are open.
