NB: I don't mean "I don't understand why people spend £25K and the rest on one day..." but things you/someone you know chose to do that looking back wasn't worth the £ or time that went into it.
Several years ago I was my friend's bridesmaid - we spent many hours in the run up to the wedding making handmade soaps as favours (including wrapping and putting twine around them the night before) for 100+ guests, people appreciated the gesture but at the end of the night at least 75% of them were just discarded, unwrapped on the tables. We were talking the other night about how, effectively, they were a waste of time and £.
DNiece got married last year and spent a tidy sum getting a graphic designer to layout artwork for the seating plan, name for each table and place name for each guest etc so all in the same font and colours - looked really lovely, however she said she wishes she would have just taken the venue up on their offer to put the table plan up on a big screen (almost like a powerpoint slide I guess) and do basic table and place names as when it was all over and she asked friends/family if they liked it most said they didn't notice/didn't remember the seating plan, or anything that was nicely graphic designed and printed 
Nevertheless, they had a great day. Think she was just grumpy it was all over and they still owed a couple of invoices to suppliers.
Don't know of anyone who has done this, however I see buying a veil from new as a waste (unless there's a v.specific one you want) as so many people sell them 2nd hand after only wearing them a few hours.
