Most online florists have a wide variety of modern flower arrangements ready to order, although some would warn you that same_day delivery might not be possible, therefore you should confirm with your florist before you buy these flowers online.
Putting it all together _ Once you have selected your flowers and vase, its time to start putting things together. If possible, first cut each flower stem diagonally about one inch from the bottom while holding the end of the stem under warm water. Use your kitchen sink or a large basin. This helps ensure each stem will absorb moisture and nutrients easily. As you cut each flower, transfer it to a temporary "work" vase, which should be halfway full of water.
