Please read my profile. I believe this is the cord used to make the ornaments seen in the back of the first image. A very kind buyer informed me that it's called "flat cord" (扁線). I will be selling this cord in 8 colors, cut to 5 meters each. Please note that I am unable to do Chinese knotting, so I cannot answer specialized questions. However, I will add more images or accommodate other requests as much as possible. Please feel free to ask if you have any questions. I have other items for sale as well, so please take a look if you'd like. Thank you for looking.
