Outdoor showers are one of life's greatest pleasures, so how about using a found shell to store your soap? You could use this idea to store little items, such as paper clips, at your desk or on a coffee table, with full of sea glass. I know I'll be incorporating this sea shell organization into my tiny apartment, even though (maybe because!) I now live far from the ocean. See another photo below.
