Give your terra-cotta pots an aged look, then trim them with sea shells.
1. To weather your pot, combine 1 part powder milk paint (available at crafts stores) with 1 part water. Apply to pot with a paintbrush. Let dry 1 hour.
2. Working in a well-ventilated area, sand your pot with medium-grit sandpaper until your desired look is achieved.
3. Gather some shells that are uniform in size and appearance. Affix shells to the rim of your pot with tacky glue or with a hot glue gun.
Let dry and plant with any variety of plant that you like. I think Echiveras would look great with this look.
