Rik started his 'single knotted wire' project with a visit to the harbour museum in Rotterdam. He met two employees of the museum specialised in knotting techniques which are used on a ship. He was fascinated by all those different kinds of objects they knotted. So he asked them if they could teach him some techniques. He knotted for three months to perfect the technique. Then he started to work on his designs. For the chair and lamp only a single wire is used and knotted in a form reflecting its maritime inspiration.
