Activity for Trina

Please let me know what you think, I made these this evening, this is as close as I could get to the color scheme, and I don't know if those will be the exact flowers but this is just a rough sketch for now.

Have any of you ladies used them for your center pieces? And If so how tall were yours? I am really in love with the feather center pieces these are made with so I am just trying to get an idea of how high they need to be.
