Martha Stewart Living, April 2004
Pick a vase about the same height you plan to make the egg (which can be any size). Use a floral knife to cut Styrofoam to fit tightly inside the vase, an inch below the top; measure height of foam. To secure Styrofoam, put floral tape over top or wedge slivers of Styrofoam into any gaps.
Immerse floral foam in water for 3 minutes, to wet but not soak. With floral knife, cut floral foam into an egg shape, molding with your hands; measure height. With pruners, trim the bamboo to three quarters the height of egg plus the depth of base Styrofoam, cutting ends at 45 degrees. Mark bamboo to indicate depth of Styrofoam; wrap floral tape around mark until it is 1 inch thick (this will help support egg). Push bamboo into Styrofoam.
Push the egg onto the bamboo, so it reaches the top of the tape. Pinch florets off stems. Push a corsage pin into the center of a floret, and affix to egg. Repeat to cover egg.
Cover top of vase with moss. Arrangement will last 3 days.
Inspired by the jeweled treasures crafted by Peter Carl Faberge around the turn of the 20th century, this "egg" is decorated with spring-blooming hyacinths and pearl-headed pins. It was created by Jennifer Pfeiffer, co-owner of Magnolia Flowers and Events in New York City, and it's easy to make yourself. Though it looks opulent, you'll need only about 10 stems of hyacinth -- each of which is a cluster of blossoms -- to cover a 7-inch-tall egg like this one.
