This thread got me wondering. My parents and DH's parents generously helped us with our wedding. We were fortunate in that they didn't have many requirements except for the guest list which we all had a hand in putting together. Both sets of parents also helped with the seating chart.
There was only one other requirement from my mom when it came to picking out flowers - absolutely no carnations. That's random, but ok mom.
What about you guys? Did someone else contribute to your wedding, and if so, what were their "requirements"?
