After crowdsourcing this one on Facebook, I came up with a better lace option.
From the website: http://www.militaryheritage.com/militarybraid.htmhttp://www.militaryheritage.com/militarybraid.htm - 1 inch (25 mm) Gold Metal Navy Braid
for Royal, British Commonwealth and U.S. Navy uniforms and decorative trimmings. This is excellent quality
metal wire lace and is often sold for many times this price.
This pattern is the Royal Navy double vellum (Orris) was used for the
past 250 years. 1 inch lace was used on Captain and Admiral coats.
In addition the American Naval officers in 1812 were often portrayed
with this pattern of lace as well.
This is the lace that appears in the portrait of Nelson., one inch wide. It is a bit pricey, but I think it will be worth it.
