My goal was to take a very trendy dark club/bar and make it a little more romantic and whimsical, without making the place look tacky. I spent $40 on gems, colored glass, fishing line, candles, and glass vases.
I ended up making tons of strands of shiny things and hung them from the trace lighting. They sparkled quite nicely in the LED glow of the club.
I also added some strands to the sconces to make them just a touch less industrial.
Overall, I think I succeeded in the giving the space little whimsy. And, bonus, I got to leave all of the decorations up! The owner quite liked what I did. :)
