It is cool “knotting”. Celtic Knots have a symbolic meaning and are like hieroglyphs in their own right. The Knot hieroglyphs from then to now may have changed meanings, but it is an age old practice that goes back to the beginning of these cultures. :)

Knotting. Was wondering what that was called. This is all very interesting. I’d love to know what the meanings of this piece were.
