Here is a tying method done in the bight to obtain the helical loop present at the beginning of this post.
It is one route among others, I am sure that some known IGKT gifted members (Alan Lee for one) are able to reach the same knot using an atypical path who could be more easy to practice.
In the meantime this recipe should do the trick.
Some months after I discovered this simple loop I learned that this structure could be regard as versatile in many ways; for it is TIB and PET(2).
Then Xarax had is eureka moment (3 and a half second) and found out that helical loops are of a special breed; since the open helix is a state of the straigh line they can accommodate any number of turns the tyer wishes to add.
Note that if you want to add more turns to your loop pay special attention to step 5 (it's time to add...)later on it will be well... too late.
It is also a good thing to inspect the loop present at the start, the tyer will have a good idea of the final dressing.
This loop can be tied in the "reverse" form see at the same post reply and Xarax's photos at number 3
I am planning to show the TIB's recipe of this loop too.

the pictures were edited since "not so blind" Xarax found a mistake in my earlier drawing, now all is in order (I hope

)
