Do some googling...

Would love to see Dave and David's work in place in my home!

Excellent ...but not free! 😉

Is the edge just drawn freehand and then push/pull?

Baz, how do you get the checking lines at the end of the board in your render? Is that also drawn in the model?... or a bump/displacement map?

It was a bump.

Thanks Dave I stand corrected

Thanks Anton that took care of it.

The scanned image isn't the same size as the originally exported template image. Resize it so it is and it'll work fine.

I did come up with something but it wasn't the easiest. Then I got onto another project and haven't returned to this.
