Scented jelly jars, like the ones found in stores like Bath & Body Works, are simple to make and quite inexpensive. Here's the recipe:

8 oz. liquid potpourri

2 envelopes of Knox gelatin

Containers (canning jars, unique bottles, bowls, etc.)

Boil the liquid, then add the gelatin. Stir until dissolved. Pour into containers and cool. You can add embellishments such as flowers or shells to the jelly while it is cooling. You may change the color of the jelly with a little food coloring as well. Once cool, decorate the containers with ribbons, lace, or whatever you desire.
