First, anchor your umbrella securely in a stand. Next, place a rubber band about 3 inches from one end of the fabric. Using another rubber band, secure the fabric, with the cinched end at the top, to the finial of the umbrella. Open the umbrella and let the fabric fall to the ground. Cut the end of the fabric near the ground. This is your pattern to cut the other panels. Cinch each panel about 3 inches from one end.
Once all the panels are cinched, gather them together and rubber band them to the umbrella finial. This creates the "flower" at the top of the umbrella.
Open the umbrella and spread your panels to cover each pie section of the umbrella material. The panels can hang freely, or group them in three sections and loosely tie the panels together with fabric strips.
To complete this fantasy look, wrap the umbrella pole with some of the tulle, securing it at various intervals with fabric ties.
