Hi,
as I decided to make "real" bonnets, I want to share my experience with you. Here is the instruction "step by step", how to attach bonnets in 1:100 scale. General idea from "Historic Sip Models" by Wolfram zu Mondfeld:
...the effect...
...and how it can be done.
1. Three holes (1, 2, 3) and the end of the thread (K). Front view:
2. Through hole 1 and then 2 (there is a single thread behind - "dotted line"):
3. Hook on the previous loop and then "go back" - we've got a new loop:
4. "Go back, go back" through holes 2 and 1 with the reverse direction (now we've got two straight threads behind):
5. Put the thread between edges in such a way to inlace these two threads behind (front and back view):
6. The last step. Put the thread below the first part of the thread, where you started (see 2)
7->1:
Best
