My save the dates are going to be exactly like the ones below and I'm not quite sure what kind of envelope to use (the wooden slices have magnets on the back so people can put it on their fridge). I want it to be sturdy so the wood doesn't rip the envelope apart and because of the size (the wood slice is about 2.5 inches in diameter) I would need small and square envelopes. Any one know of where I can find sturdy envelopes (preferably not just plain white) for this in a small size?
Let me know! Any help will be appreciated.
