All - about £1200, that was 26 years ago.
You pull in every favour going - you don't need posh cards when everyone has a media app and photoshop - you just need one lot of posh(ish) card and some envelopes
Flower - we got married at Christmas, so the church was already decorated and my friend made all the table tops and garlands - that was her present to us
Didn't need limos - everyone we knew had a half decent car.
Favours - if you want that sort of thing - easy enough to make with a few yards of netting/silk, some ribbons and almonds
Friend took the video, we had disposable cameras on the tables. We did pay for a pro photographer though.
Cake - my mum made it, MIL decorated it.
Don't bother with a sit down, we had continuous buffet made by MIL, aunties, neighbours
Hall Hire was nothing as it was annexed to a pub and the land lady loved us, she know we were a popular couple and she'd more than make her money on the bar, so that was free hire
DJ was a mate, that was free
Wedding rings are cheap enough, 100 quid a piece if that, plain gold bands, I don't like fancy.
My dress was the one out lay - 400 quid and that was 26 years ago. Cant remember how much 6 x tux was for the grooms party.
All in all it was less than £1200 - and I always get a lot of stick, we both have enormous families, DH plays a lot of sport, he is very popular, so we had over 700 people invited, of which around 400 turned up.
We did not have a free bar, the land lady said not to, people always abuse your hospitality.
fantastic night :-D
