Whichever way you decide to go with your flowers, a lovely idea is to try and tie your whole theme together so if you're going for roses, then have a rose design featured somewhere within your headdress. Look out for a company who can work with you and your designs and most importantly your budget to create that one_off, bespoke creation just for you.
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.
