Keep at it brother! And many here certainly appreciate your efforts, starting with figuring out the lopin.
Previously posted, but relevant. Top: Washington or American Flag Left: Double 81 Bernard Middle: Extra-Fine Crolle Right: Chain

Of course how the lopin became the finished pattern is the hard part

And there were multiple patterns referred to as
Etoile, Washington, and Chain or Chainette
This is the sample display of
Joseph Juleinond de NessonvauxInteresting that the Chain segment appears with the
Corche and
Legia
Etoile and Washington variants
Desire Mineur, of Prayon, Liege, claimed exclusive rights to "Chain-pattern" damascus in 1904, and the process was no doubt a carefully controlled secret
Another interesting Chain pattern by
LePage, with prominent 'Stars'
The creativity and artistry still astounds me!!
