Acquire the type of artificial flowers you want to use in the decoration. Pick realistic-looking faux flowers to coordinate with the overall decor style or a space or table, such as orchids for a tropical theme, or red roses to create an aura of romance.
Obtain the flower vase of your choice for your floral arrangement. Choose a small, medium or large vase depending on the desired size of the decoration. Select a vintage porcelain vase for an elegant look, a shiny silver vessel to create a modern style, or a hand-painted ceramic vase for an artistic vibe.
Cut a piece of florist's foam to fit the bottom of the vase using a craft knife. Place the cut-to-fit piece of foam into the vase.
Insert the faux flowers into the vase, pushing the stems into the foam to create a secure fit. Arrange the flower stems according to height or color.
Add decorative elements to the vase. Accent the flower arrangement with sprigs of artificial baby's breath for a fresh look. Decorate a birthday party table arrangement with a festive balloon on a stick. Create an eclectic look by adding curly willow branches or thin bamboo stalks to the arrangement.
