Keep or give this notecard celebrating the nature of the Salish Sea. All my notecards measure 4.25" x 5.5" (A2). My Tidepool Nature Studies Series celebrate characteristics of the natural world of the Salish Sea. This is a depiction of the pacific northwest tidepools I visit daily. As always, at least 10% of sales (more when I can manage it) are donated to indigenous organizations and local nonprofits working to restore our Salish Sea.
