These were super inexpensive & quick to make. The glass vases, mirrors and flowers were all purchased from the Dollar Tree for $1 each. The flowers actually came off a Hawaiian Lei that I took apart. The lighting is a submersible led light. I've seen them on eBay - a dozen for $15. These will be on a white table cloth (that isn't wrinkled like it looks in the photo). Just place the light in the vase, add water and then place the flowers in the water.
What a fantastic Kate Spade bridal shower. I love the cupcake bar, the decorations including the gold mylar "XO," balloons and the pink and black tables. See more Kate Spade party ideas at CatchMyParty.com
