Add a layer of green pebbles to the bottom of a glass vase. Stack the lemons on top of the pebbles, creating another even layer. Wrap the ribbon around the edge of the vase and tie it into a bow.
Fill the vase with water for a different look. Or slice the lemons and allow the slices to float to the top. Add the pebbles at the bottom and the ribbon around the edge to complete the look.
Wrap the lemons individually with ribbons to create yet another look. Place the lemons in the vase and sprinkle the pebbles throughout the stacked lemons.
