Glossary: Decorative Knot Design Vocabulary

Decorative knot designs run the gamut from jewelry, home decoration, clothing, general ornamentation, and art with the occasional crossover into practical knot utility.

Ornament Branching off from the idea of decorative knots, most of the things one makes with decorative knots are "ornaments".
Hanging Ornament a large proportion of knotted ornaments are made to be hung from a loop at the top. It could be suspended from a festive tree branch, a flute, or the hilt of a sword.
Wall Hanging It is a rare Asian household that does not have knotwork hung on a wall somewhere in the house. Indeed, culturally it is important enough that the various Tiangongs, the Chinese space stations have each (?) had at least one (I have a small collection of images of knots installed in more than one Tiangong, but the articles I clipped can no longer be found on the news sites where I saw them originally ☹️, for now here's some video proof)

Is tapestry a better term? To me, a tapestry does double duty of decorative element and insulation/sound absorption. Most knotworks don't have the bulk to fill that aspect?
Tassel a "tassel" might be considered just a thread cluster hanging from the bottom of a knotted ornament, or the entire ornament. This is for you to decide.
Spacer a term from beading: a spacer is usually a smaller or simpler and often cheaper bead used between the larger, glitzier design elements to give visual breathing space to the composition.
