hardwood floor repair

https://brightquillio.com/s/02Nu-JRIuaFlznNWrI3C3

We've got a gouge in the living room floor from where the couch leg finally gave out. Hardwood floor repair isn't just about filling the hole; it's matching the grain and stain so the fix disappears. I'm trying to learn the process, from steam-ironing out the dent to blending the new wood filler, so it doesn't look like a patch job.
