Photoshop :: How Do I Make A Font Look Like It's "stamped" Into Texture?

I'm making a website based around leather products. So my site design is based around leather.

I've got a light brownish/red leather texture for the main area of the site, and I want to have some text that looks like it was stamped into the leather, or burned into it, etc..

I've tried simple stuff like a reverse bezel or just an internal shadow in the top left.

Those suggest the letters are sunk in, but in no way look like they were pressed into the leather or burned.

I've tried using the burn tool but it doesn't look natural at all.

I'm also trying to get other leather effects, like punched holes, or sewn edges, or pattern stamping etc... Anything that might be done to leather.
