Weddingbee boards

I am actually thinking about using tulips for my centerpieces -- white only French tulips (those are the long ones).  So the gorgeous vases I bought on sale last week from Pier 1 -- I should say first that we're having a tapas-style dinner/reception Sat. nite in June at a loft in NYC so only about six small-medium round tables and two high-boys (tables) -- are about 16 inches tall (glass with a stem bottom, and just above the bottom, a shiny silver ball, followed by the glass urn).  So the urn measures 10 inches high by 10 inches wide.  Sooooo -- my florist thinks I'll need 40 FORTY of these tulips per vase (and I have six vases.  She says $90 per "arrangement" because each tulip stem has to be wired.  I dunno what I'm doing, to be honest! Just trying not to spend money like some drunken sailor.  I am so lean about so much else about the flowers -- just one giant arrangement for the bar, a bouquet for me (150), for my MOH (100ish) and for three BMs (75 each) and boutonniers.  A lacey arch at the altar on bamboo poles (handmade by florist/me) that will be carried down the aisle by my wedding party, and lots and lots of candles (the loft has lots of track lighting on these super high ceilings and terrace - all on dimmers).  So far, no adornment down the aisle.  Am I nuts? Now I'm worried about what some of you are saying about tulips and freshness and opening up too fast!
