Vintage Boho wedding

Hi all! My wedding was supposed to take place earlier in June but we are delaying until next June. With the change, I also decided to book a venue I actually preferred as I felt like we were settling due to price. With this, I’m completely changing everything lol and going for a more vintage boho look. Instead of doing the vintage goblin type cups, which can be pretty expensive, I think I’ll be going with regular cups, plates, etc. but still want to add a vintage flare to the table. I thought I could put tea light candles in this type of glass that I’ll be on the hunt at thrift stores for. Our tables are 9 ft long farm house tables and I plan on doing at least 3 bud vase flower arrangements on the table. How many candles do you think should be per table?
