I started by placing a sheet of sandpaper on my flat table saw and trying to sand off all the high spots in the same plane to make it look really crisp.
But it didn't look great. Some of the letters were shallower than others and didn't get polished up.
So I switched to a dremel with a little abrasive bit and traced the tops of the letters. The dremel produces different facets, so it doesn't shine for the camera shooting from a single point. But it looks pretty good in person when you have two eyes and see it from different angles.
And I folded the loops back a little flat to grab the neckerchief securely. I gave it the hop up and down test, and it stayed put.
I'm pretty happy with it.
