The ancient art of topiary involves cutting landscape shrubs and plants into decorative shapes. Using craft supplies and silk flowers and foliage has become a common way to create centrepieces and pieces that can be used in home decor. Making your own topiary trees and centrepieces is inexpensive compared with buying them and allows you to create exactly the look you want.
Fill a 6-inch clay flower pot with floral foam, fitting it snugly into the pot. Insert a 12-inch wooden dowel into the centre of the foam about 4 inches deep.
Insert a 4-inch foam ball onto the end of the wooden dowel, stopping when the dowel is about 3 inches into the ball. Don't push so far that the dowel pokes through the top of the ball.
Cut the flower stems with the wire cutters so they are 2 inches long. Insert the flower stems into the foam ball, covering it completely. If the ball's surface is showing between the flowers, add some greenery such as ivy leaves to fill in.
Place some Spanish moss over the top of the flower pot to cover the floral foam. Add some green leaves on top of the moss. Tie a bow around the dowel below the ball.
Fit a polystyrene cone snugly into an urn-shaped container about 4 inches in diameter. Use a container that is in proportion to the foam cone you are using. Cut pieces of floral foam to fit into the container around the cone and secure it, if necessary.
Glue unshelled walnuts onto the cone. Start at the bottom and work over the entire cone, covering it completely. If there are any spaces left between the walnuts, fill in with silk leaves or craft moss.
Glue craft moss around the base of the cone to cover the top of the container. Ivy leaves or another kind of leaf could also be used around the base of the cone.
Use any type of container when making a topiary tree and centrepiece. Apply spray paint to the foam ball and cone before covering them with flowers or other items.
