All the flower arrangements I want are pretty simple and I'm sure my family and I wil have no trouble putting them together. Oh wait, I need to share my bridemaid's bouquet idea: I'm going to carry the long stem bunch of calla lillies and each of the bridesmaid will carry a bouquet of only one kind of flower with long stems similar to mine. But each girl will have a different flower. One with tulips, one with roses, one with amarylis etc. They will all be white and similar to mine but smaller and maybe a little shorter stems.

Anyways, so with things being simple, it seemed logical to just buy the floral in bulk from Sam's (by the way I think that's the cheapest place to buy flowers) and put everything together myself. Here's my worry: I've read that white flowers are the most difficult towork with because the petal can bruise more easily. I've also read read that you should be sure that you're florist carries the flowers to the site in a refrigerated truck. Obviously we will not be able to do that. My flowers should be inexpensive to do with a florist since they're simple but I'm sure it will be more than doing it ourselves. Especially since I would like to do something like in the picture. Is anyone else doing their own flowers? Anyone using florists because of the same concerns I have?
