My friend living in NY from Germany just sent me the greatest party invite ever. She took a photo of her fridge with word magnets about the party holding up a post-it with the time/date and a subway map with a little red sticker over her address. The photo is a webpage and when you click it, it sends you to a google map with her address.
It’s so much cooler than it sounds and the whole thing probably took about 10 minutes. I’ll post it when the party is over and she has moved, then the privacy thing won’t be an issue.
