So we're throwing a party next month- it's sort of an open house/ housewarming party, but I will definitely spread the word that we don't want presents- hopefully my MIL won't tell her whole family we need more stuff; she's a weirdo about presents, as some of you know. The reason we're having one is because EVERYONE we know keeps asking us when we're having one, so we figure we'll invite everyone over, feed them, and send them on their merry way. However, the GL is at about 65 people right now; it'll be a come & go as you please type of affair, so I'm not worried about that many people in my house at once, but I do worry that invites are ridonkulously expensive these days. I would send out an e-vite, but A) I LOVE paper, so I wanted to send actual paper invites, and

some of my older relatives don't have computers. Would it be bad to e-vite some of my guests and invite the rest via snail-mail? That way, I save on paper but still get to send pretty invites out, but for those that are technologically savvy, I can just shoot them an equally cute e-vite ASAP. My theory: those who get e-vites don't interact with those who would get e-vites anyway, so it's a win-win. Thoughts?
