We ordered our Real Touch Bouquets at save-on-crafts.com... They were $16/piece. These bouquets are for the bridesmaids and then will go into the centerpieces. We will be wrapping them in black and pink ribbon.
We got the vases at Ikea for $4.99/each.
The submersible LED lights and expandable water beads are from Michael's.
Here is a mock Centerpiece without the ribbon on the bouquets.
