Similar to other Northwest Coast artists, Seaweed did not sign his artwork. However, it can be identified through his specific technique. Seaweed used tools, such as a compass and straightedge, in order to make precise and symmetrical compositions. His carving was so accurate that the surfaces are smooth without discrepancies. Small pencil lines that can still be seen on the back of objects inform of his process, while his tendency to paint the interior of his masks in addition to the exterior help researchers identify his work. Seaweed's artworks can be best identified by the eye technique. Seaweed created three concentric, symmetrical circles using a compass, and the point holes created by the compass can still be seen on surviving objects. The eye was often traced with a red eyelid line, setting him apart from his contemporaries.
