When done, I used an Exacto to make marks I HOPED would imitate the grain brought out by the stain. It worked and even I have to work hard to find the repair.
Now there’s some creativity. One time I messed up with the router and took a good sized gouge out of a desk top. I filled it with wood putty and drew the grain with a pencil. After finishing it, you’d have to look for it to find it.
