Starfish Candle Centerpiece Centerpiece IDEAS! Help!?

Centerpiece IDEAS! help!? - starfish candle centerpiece

So I expected and I bought all my parts center. but now I'm with doubt.
These are my colors:
Blues (aqua blue sea)
Ivory
Yellow
Brown (Brown is not my wedding flowers)
I have a theme wedding beach, so they have a bowl, I vases tall and thin, but they are square, flat rocks on the blue background w / w sand dollars between rocky, / a long candle. Well, I thought I would not be the Blue Rocks W / forsytria spray and not the yellow light and sand, not dollars. but I want to hot glue starfish and sand dollars outside of the cup ... What do you think? Thank you!
