Step 1: Find a bundt pan at your local thrift store or use one that you already hate (oops.. I mean have). Note: Make sure your umbrella will fit in pan hole.
Step 2: If you don't love the color, spray it with indoor-outdoor paint like Krylon in "Bahama Sea".
Step 3: Drill a few holes in the bottom to allow water to drain from your soil. Note: 4 or 5 holes should be plenty, too many holes will leave your soil dry.
Step 4: Remove umbrella from patio. Line up bundt pan hole over patio table's hole and slide umbrella down through bundt pan center.
Step 5: Fill with soil and flowers or succulents.
Now you have a "delicious" planter that's at the center of a future patio party!
