Well, this was fun to try to take a picture of, what with my nutzo choice to use iridescent metallic thread.  But this demonstrates that it does look good in metallic, though!

In the image, I stitched this at a size of 1½".  This is a regular ESA keyboard font, and it's for flat work.  However, if your heart desires the same kind of thing for 3D puff, then I've got something for that, too.  The puff ones can't be made in a keyboard version, because the settings in the end-user's software will mess with the density and, in some cases, the pathing as well.  So I have them all zipped together as individual dst files to keep that from happening.  They're planned at a size of 2" tall, and there's a regular puff version, as well as a bordered puff one.  Have a look here: 

For Wilcom users running version 8 and above.

WARNING!    For Wilcom software ONLY, please do NOT buy an esa keyboard font if you aren't a Wilcom user. It will not run with software other than Wilcom. Keyboard fonts are specific to software type, and not at all like stock designs that will run on anything.
