For a recent dinner party, I constructed arrangements of single roses on gold wooden planks (see An arrangement of Single Roses: Simple, Upcycled and Breathtaking). For that original arrangement, I used 6 roses for each 6-foot section of gilded wood.
This arrangement takes inspiration from that one, but uses 10 single rose blossoms for each 6 foot wooden plank. This leaves almost no whitespace between the individual vases of rose blossoms and creates the illusion of an endless row of rose blossoms.
Simple to Wow? You decide.
