Question
What would you consider a good wedding centerpiece for a July wedding with an art deco theme using callalilies?

Answer
I would began by looking at a reasonable retail store for vases that
have character. I love the art deco look and I am not sure what era your looking
at doing. Once your set on containers, you may purchase different colored wire to
your arrangement.  Calli lilies can be wired to move different ways and you could
ask your local florist. Without wire they can also give a interesting look.
