We gave these terra-cotta pots an aged look, then trimmed them with seashells.
To weather a pot, combine 1 part powdered milk paint (available at crafts stores) with 1 part water. Apply to pot with a paintbrush. Let dry 1 hour.
Combine 1 part lime powder (find it at garden centers) with 2 parts water; brush on over paint. Let dry 1 hour.
Working in a well-ventilated area, sand pot with medium-grit sandpaper until desired look is achieved.
Gather shells that are uniform in size and appearance (or purchase them at crafts stores or online). Affix shells to rim of pot with tacky glue; employ tweezers to adhere the smaller shells.
