Step 8: Texture the Sugru

Picture of Texture the Sugru
Using the drinking straw, press circles into the Sugru layer on the "bottom" and "top" pieces.  Make the circles tangent to each other as much as possible.  The only parts to avoid with the straw are the two side fins on the "top" piece.

Once you are done, let the Sugru cure for 24 hours.
