Was the STD card sent out to other friends who could also be helpful in other weddding necessities? Like friend #3 who is handy with a camera , and friend #5 who is a dab hand with the Fondant Icing, plus friend #8 who has a naice car?
All your wedding 'essentials' covered by friends and acquaintences who have a free day as they were/are exspecting a formal invite to the wedding
Surely though, the STD card can't have been for the same day/date as the actual wedding ? The venue would need decorating the day before as there isnt enough time on the day itself.
I have been to a wedding where I didn't attend the ceremony , and cooked all afternoon for the guests . I was asked and was happy to do so , and got to enjoy the party afterwards , which was way more fun than the church bit.
Maybe Slyvian figurine based sock puppets could be placed in the church and the venue , peeping round pillars and out from behind flower displays?
