Fresh flowers get plenty of centerpiece play, but who has the time -- or funds -- to make a bouquet for every birthday? Try this low-maintenance fill-in by fashion designer Isaac Mizrahi. Print out pictures of flowers and butterflies, then clip them into a store-bought photo hanger and place in a flowerpot. You can even quickly spray-paint a basic terra-cotta pot for a new look. When guests are gone, move the "arrangement" to a windowsill or coffee table.
