For an informal profusion of blooms, cut the stems short and at staggered lengths. Another good trick (for this and many other arrangements): Let flowers and foliage gently hang over the edge of the container. This eliminates the dividing line between vase and arrangement, resulting in a softer look.

A plastic-wrap liner protects the container from scratches and stains. Shallow vessels such as this bowl require a frog to hold stems upright and let the flowers spread out evenly. We used about two dozen roses.

Rose Dome Arrangement How-To

1. Line a container with plastic wrap. Using floral adhesive, secure frog in container. Measure and make note of distance from center of frog to rim of container.

2. Fill container two-thirds full with tepid water. Add a packet of flower food.

3. Cut stems of 3 or 4 red roses slightly longer than frog-to-rim distance. Remove foliage from parts of rose stems that will stand below water level. Insert stems along perimeter of frog.

4. Cut 3 or 4 more red-rose stems to same or longer measurement, and insert at center of frog.

5. Cut remaining roses, varying stem lengths as desired, and fill in arrangement, creating a loose dome.

6. Retrim stems of any flowers that project too far.
