How to create a most beautiful floral arrangement / centerpiece. First start with a container that is low. If the container is not one that is decorative then when adding the greens to the container place them at a downward angle so as to camouflage the container. For fresh bouquets you will need a brick of wet floral foam and soak it accordingly and place in your container. Add a nice mixture of evergreens like firs, cedars, pines. Then add some hard goods like pine-cones, fake berrys (or real), shinny glass balls and pretty ribbon picks. Lastly pick the flowers you would like in your bouquet. Most traditional are red and whites, but you can do whatever you want! The longest lasting for the holiday season are carnations, poms, alstromeria lilies. But you can also add other varieties like lilies, gerberas or even star of bethlemem and of course roses. However you build it, variety can make the prettied centerpieces because they allow for lots of different textures and colors. Be sure to design the bouquet low so people can see over top of it to visit. Check for water daily. Most important have a cheery and merry fun time!
