Focus on strengths.
Don’t just assign tasks at random to appease people. Make the most of the talents and interests of your loved ones. Does your sister have amazing handwriting? Ask her to address save-the-dates or hand-letter table numbers. Is your grandmother an unparalleled baker? She can make treats for the rehearsal dinner.
Do it together.
I like getting a group together to cross something big off the list. Ask all the cousins to come over to help wrap favors, make centerpieces, or double-check RSVPs, for instance. Do it over a bottle of wine or some pizza and it’ll be a really good time. You’ll get to bond, and—bonus—oversee everything without feeling like you’re micromanaging.
