The strings that go around the ears to hold a mask to your face can be useful. It can be surprising how strong the loop is once made with a #ZeppelinBend. A mask string made into a circle with a #RosendalsKnot is much stronger than a rubber band. Eventually I'll have to design a lesson to learn the knot along with some of #DirectivesAndOperations from #OgdensBasicEnglish. I have a lesson for the BowlineKnot (もやい結び) based on a story about a rabbit in a hole coming out to go around a tree...
The most attractive *functional* knot. Prove me wrong. Look at that symmetry! The zeppelin bend is used to join two ends of rope. Fairly strong, and easy to untie after loading.
