Showrooms are fabulous ways to be inspired and to see items up close. If you've ever been to a bridal expo, then you know first hand what I am talking about. However, just because you see something on full display and looking fabulous in a showroom, doesn't mean you should duplicate it verbatim.
The tablescape on both tables are gorgeous to look at but not at all practical. You want to ensure that your budget-breaking wedding not only looks good but is also very practical:
Centerpieces should be 12 inches or shorter. Otherwise they ought to be 24 inches or taller. Anything between 12 and 24 is a no-no because it blocks your view of the person across the table.
Showrooms break this rule all the time because it doesn't apply. Passersby are walking and standing. They break the rules on purpose. Don't you do the same!
