I like this idea. It could be used for decoration on a spooran;
belt; hat emblem; or even a sleeve for the sgian dubh
Is it possible to put the xmarks pin in a hydraulic press of sorts
and stamp out the image onto the leather form?
The small fine scrolling design might not imprint to well.
But looking at your pix the bold xmarks features are well noted.
Then trim to fit and glue it to a pin/retaining device.
Possibly doing multiple impressions on a belt for an xmarks belt.
Or one could go really wild and have a laser burn the design into
the leather if such a thing is possible.
