Wedding bouquet flowers help?

Try Ling's Moments. I've seen them on Amazon and Etsy. Also, there is a seller on Etsy who puts these together for very reasonable prices. Not sure if they would sell you the bulk flowers, but it's worth asking, since these are the kind of flowers they do. That shop is called DressMyWedding. on Etsy.

The other thing you can try is just a simple search for "calla lilies" or "red calla lilies" and see what vendors come up.

I'm using purple calla lilies in my bouquet!!
