My FH and I are on a very tight budget and are planning a very small wedding (75 people) in the summer, in a church with an outdoor (hopefully) reception. He had an idea that I LOVED the other day to make it an old style family picnic theme with red checkered table cloths, in a park so the kids can all play while we eat, drink, and dance. To go with that theme, he wanted to do a family pot-luck type of thing instead of bringing gifts (cheaper for us, cheaper for them, and our families both LOVE to cook and eat). However, since it's considered rude to even mention gifts on an invitation, even if you don't want them, how would we get the word out? I'm concerned that if we go by word of mouth, we will end up with a ton of the same few things. Neither of our families are picky about ettiquette and only our closest friends are coming. They would all love the idea, but even if they don't care, it feels tacky to me to request food on an invitation. How do we get around this? Is it possible?
