Choose a container that will complement the shape and color scheme you have in mind. If you are just starting out, go with a traditional size vase __ not too tall, and not to squat. As a general rule, your container should be about one_third to one_half the size of your finished arrangement. So, for a vased bouquet you'll need mostly flowers with longer stems. A smaller bowl or basket is fine, too. You'll simply have to cut stems shorter and may need floral foam to help position each bloom. It helps to start with the simpler designs and work your way up, and a vased bouquet is often recommended for a first project.
Purchase synthetic flowers instead of the natural ones. Synthetic flowers may cost a bit more when you buy them in bulk, but they could save your money as they last longer than the natural ones. Here is how it will be worthy to buy the synthetic ones; when you buy the natural flowers for flower girls, bridesmaids, as well as for yourself, they tend to whither rather quickly, more so in case of indoor weddings. As a result, you may end up buying more fresh flowers. One more advantage of buying synthetic flowers is, you can chose any petal color, any bloom shape as per your preferences and thus giving you more freedom in planning the decoration at your wedding.
