Here is another variation of this round turn method due to Xarax which seems to be first presented in the IGKT forum in 2010. Many of the very old items no longer have important images, but this was more recently discussed in 2024. https://discourse.igkt.net/seppelin-360-bend/7750 Effectively, we do “half a round turn” to get a version usually called a Double Zeppelin Bend B2.
Before we move on to the related Blimp Knot, we should note that this construction does not truly give a Double Overhand Knot in each of the cords separately. Instead, it is merely a more complicated way for two Overhand Knots to interact. It has been recently proposed that this Double Zeppelin Bend B2 instead be labeled a Zeppelin 360 Bend by Mark Gommers on the IGKT Forum. He also wants to rename the Double Zeppelin Bend B1 to now be a Zeppelin 540 Bend. The motivation for this notation is the wrappings of the start of each.
I am not opposed to the renaming for the Double Zeppelin Bend B2 because it does not involve any Double Overhand Knots. However, I think I will not switch the name of the Double Zeppelin Bend B1 because it does involve the interlacing of two Double Overhand Knots. Next, we move on to how to get the related Blimp 360 Knot which I like a lot.
Zeppelin 360 Bend ……………..Blimp 360 Knot
Here are the tying instructions for a Blimp 360 Knot. Notice that we begin with a loose, horizontal Overhand Knot. Then we move the standing part down and flip the bottom of the Overhand Knot up. We finish with the free end as indicated.
