Place a rubber band around the middle of a pink grapefruit or orange. Use it as a guide to make an even ring of cloves around the fruit, piercing the skin first with a wooden skewer or nail. Remove rubber band, and make additional rows. If desired, use a hot-glue gun to attach star anise; let the glue dry.
To encourage pomanders to dry evenly and retain their scent for up to one year, shake each in a plastic bag of powdered orrisroot (available at health-food stores) before displaying. Stack the pomanders in a pyramid, using clear plates between the layers and tucking in greenery, such as this mountain laurel, as you go.
