like many of you, we were invited to our own wedding. not even really consulted on anything - flowers, number of guests, venue - we did have a church wedding, and I did choose my own dress!
For DD, we were also invited to it. DH paid for drinks, I made all the wedding cakes, about 5, and did the flowers, but they paid for the flowers. DD and SiL paid for everything else. I was also asked to make "flower-fetti" out of flowers from our [then] HUGE garden.
We also paid for hotel rooms for her two brothers [and DS1 was flowen by us from Argentina], adopted grandmother, DS2's ex andhis son, etc.
It was a lovely event, but I felt a little left out as I had expected to do a little more of the MoB stuff. Everyone else had a great time, so was happy with it.
Enjoy wonder - your DiL to be is involving you, since she is keeping you up to speed, just ideas past you rather than "advice"...
