The ryijy - wall rug is an old traditional textile which was already used by the Vikings as boat covers. In Finland as well, ryijys were used as covers and warmers. Later, ryijys were started to be used as blankets in beds, and only in the 20th century did they become art to be hung on walls.

The ryijy is weaved in a loom by tying the knots one by one onto two warp threads in rows and weaving wefts between the rows. The ryijy can also be made by sewing onto a base cloth.

The ryijys of Studio Taina Otsamo are made with wool and linen. The linen provides the pile surface with shine and deepens the colour. The knots in these ryijys are also tied differently than in traditional ryijys, creating a denser pile.
