DIY: Pressed Seaweed Prints

As a native Cape Codder, I’ve always been fond of seaweed. So when I ran across designer Karen Robertson‘s pressed seaweed DIY on Garden Design, I had to give it a try.

Above: Any project that starts with “Step 1: Head to the beach,” is going to be A-OK with me. Here I employed my little helpers, Oliver and Solvi, to assist in finding seaweed specimens. We carried them home in a bucket of clean seawater.


• Seaweed
• Bucket of seawater
• 140 lb. watercolor paper
• Cardboard sized to cover your paper
• Weed cloth or other mesh fabric sized to cover your paper
• A medium-size artist’s paintbrush
•Two pieces of wood sized to cover your paper
• Something heavy, such as books, to use as weights 


Step 1: Gather your specimens and then place them in your sink or a bucket filled with clean seawater.

Step 2: Fill another bucket with two inches of water. (Instead, I used the other half of my double sink.) Then slide a piece of watercolor paper into the tub and arrange the seaweed on top, keeping both paper and seaweed submerged.

Step 3: Carefully lift the paper out of the water, tilting it this way and that so the water drains away but you still maintain your design (more or less). Using a small brush, reposition the seaweed into the desired composition and brush away any unwanted bits of seaweed and sand. 

Step 4: Carefully place your arrangement on a piece of corrugated cardboard and gently place a piece of mesh fabric on top. You can layer several prints this way.

Step 5: Place your stack of prints between the two flat boards and put something heavy on top, such as a brick or your Introduction to World Art books. Wait several days, depending on the relative dryness of your climate. A fan also helps.

Step 6: After several days, remove the weights and layers to reveal your prints. (If they’re not fully dry, it’s fine to put them back under the weight.) Using Google, I looked up the names of my specimens and wrote them in pencil.

The Results

Above: Two framed prints now grace my mantel. The most delicate specimens and simple compositions turned out to be my favorites.

Above: After trying this project, I have one note to add to Karen’s tutorial: More translucent and delicate seaweeds make better (and less messy) prints.
