All his work abounds with references to the myths and ideals of past cultures. At the end of the 1960's, he began his work as an artist with textile creations for exhibitions and private and public commissions. Riis himself weaves his tapestries by hand on a vertical loom (high heddle). This almost obsessive need to be involved in the manufacturing process allows for an almost ascetic intellectual journey.
Weaving becomes a real catharsis for Jon Eric Riis. He uses a cotton warp (almost 5 threads per cm), and also likes the interaction of silk and metallic threads. He often enhances his creations with embroidery, crystal beads or coral beads. He uses colour gradients to create precise and always surprising descriptions.
