Abstract
An insulation sleeve for a heated beverage cup. The sleeve is formed from spathes of a raw husk material, such as corn husk. The spathes are attached such that end portions of the spathes overlap to form a generally circular form sized to fit about and vertically support a typical frustoconical beverage cup. The sleeve may be further formed to have a generally frustoconical shape to fit the corresponding frustoconical shape of the beverage cup. The spathes may be dampened to assist in forming the sleeve into the circular or frustoconical shape.
