Regarding the loops at the second post.
We have three more lend-of-line loops, based upon the two interlinked nipping loops, Pretzel-like nipping structure. Here the working end coming from the eye enters the Pretzel central opening ( where it is nipped most effectively, being encircled by both nipping loops) from the opposite side, from the one shown in the attached picture of my previous post.
1st loop. The coil-like collar structure of this loops seems poor, in comparison to the fine nipping structure.
2nd loop. The coil-like collar has an orientation that makes the second leg pass underneath, and be squeezed by the first leg, in an effective way. Perhaps it is the vertical orientation of the nipping structure that justifies the use of a not-proper collar here. ( I like this loop, and I suggest you should name it. Together with the "Lee s Pretzel loop", the second loop that you presented in your previous post, these are the best lops of this thread. ( I think that at the "Lee s Pretzel loop" the second leg of the collar is squeezed under the first leg more effectively, but the difference might be insignificant.)
3rd loop. I see no reason to pass the working end through the Pretzel like this...Both legs of the collar should penetrate the double nipping loop, otherwise a gret portion of the true potential of this structure will remain unused.
