FH and I will be making donations to a couple favorite charities instead of doing favors. Initially I thought we could note this on the menu cards, but we may not end up doing those. Not sure if we're going to have programs either.
What would you suggest as a way to let guests know at the wedding that this is the deal?
ETA: Thanks to the perspective and advice from others, we will make our donations separately and just skip favors entirely for the wedding! Thanks guys!
