But if the rustic box isn't your style? A wicker basket. A silver tray with lower sides. A glass bowl with moss up the sides to obscure the "mechanics" of the arrangement. A decorative ceramic serving dish. I love the subdued green and white look.
Christmas door "wreath" or wall decor: Goodwill frame, painted with Christmas bells and sparkle ribbon added. Would be cute for any season with different colors and hanging items! Totally my idea of a wreath :)
