Recently I realized Jane Zimmerman has made some of her writings about or nue available for free online. I was particularly interested in her article about doing or nue on needlepoint canvas or Congress cloth. She tells you exactly how to do this, from the types of metallic thread to couch to the number of plies of the various silk brands available when this article was written. https://janezimmerman.com/Site/Techniques/Or%20Nue-canvas.pdf If you want to read what she says about traditional or nue, here's the article. Note that the articles are nearly the same but there are some tips that apply only to those working on needlepoint canvas or on linen fabric. https://janezimmerman.com/Site/Techniques/Or%20Nue.pdf
