An oversize eggshell filled with flowers unites two symbols of spring in a single arrangement. Look online for blown-out ostrich eggs (which cost about $10). Using a tape measure and a pencil, mark dashes around the top, each about 2 inches from the existing opening. Connect the dashes with thin painters' tape, creating a circle, as shown. Fit a Dremel drill with a cut-out blade. Wearing protective goggles, hold the egg securely in one hand while using the other to drill just inside the taped line. Remove painters' tape. Next, tape fine-grit sandpaper, right side up, to your work surface. Run the cut edge of the egg over the sandpaper to smooth and level it. Use floral adhesive to secure egg to a small compote and to secure a narrow vessel inside the egg. Fill vessel with water, and add flowers.
