One of the things I do on the odd occasion is to make flowers or some such out of knots. As a personal test, I make them without gluing, sewing or other artifice other than the interwoven knots themselves. Mind you, I don’t even bother telling this to most people, as only the end looks matter to them.
This was a new idea I had for making a wreath base to be adorned with knotted flowers and leaves and the like. The ring is about 1″ in cross section and about 7″ outside diameter. It makes a very substantial and well formed base to build on. It could be made to any reasonable size by maintaining the same proportions; it is still self-supporting since the strength increases with the size.
Your mission for today … if you chose to accept it … is to figure out how it was made. I will give the answer in a few days, but will leave you to simmer til done.
Thank you for dropping by; come back in a few days for the answer in a comment under this knot.
