Please help with this spherical knot

[Omphaloskepsis]

Hi,

I've seen this tieback on the internet, have got a number of knot books at hand but I cannot get the same result as in the picture, I've tried a 4-pass 3-lead 4-bight turk's head following this video (https://www.youtube.com/watch?v=UNS43htgqMA) but what I made is different from the tieback above, here is mine. I also tried a doubled Chinese button knot, but again, it's not the same... I'm a novice but if anyone could give a hint on what type of knot this is and how many leads and bights there are (if it's a turk's head, I guess there is an expansion too?), I think I could make one with the help of the books I have.
Many thanks in advance!

To my eyes, it looks a lot like this

Thank you very much for your reply. After comparing your suggestion with the picture I finally understood what is the difference - the direction of the bights
Further searching I found a flat mat with a thump knot, I made it and tightened it into a ball (not that accurately though). Looks like that's it. Though I'm going to try tomorrow a 5-bight 4-lead turk's head, as the 3-lead one again looked much like this when turned upside down!

Hello Omphaloskepsis.

I am wondering if what you are seeking is the Double Monkey Fist knot. (ABoK# 2206)

Have a look at the tutorials here http://pineappleknotstutorials.over-blog.org/article-monkey-fist-90253646.html

There are plenty of "globe" knots around and or Pineapple knots should you care to upgrade.

Hello,
My earliest guess was the monkey fist knot but it's different from my picture's one. I had stopped at the turk's head knot but I knew something was wrong as the bights at the bottom of the ball looked fewer than at the top so was wondering if there was a way to make the number of inside bights fewer than the outside ones (which is not possible in the turk's mat). As I discovered the thump mat (ABOK #2360) with its 3-inside bights and 6-outside bights, I tightened it into a ball and it worked! Here is a video from youtube with clear instructions in case someone likes to make their one! https://www.youtube.com/watch?v=CklSFklW8yk
Thank you!
