The sorce pic was sent by a friend who isn't sure of the origin I'm afraid, but it looks like a fairly recent picture. Seems like an embroidered monogram using a script typeface.

I'm looking for this font, or something similarly simple and elegant.

Thanks for your help!

Sorry, not finding a match.

Embroidery typefaces don’t always correspond to typefaces used for traditional print or digital design—they are often specific to the embroidery world.
