Texture Question

Hi Folks,
I am new to Rhino and am enjoying learning the software.
I am trying to attach a material to a wall and am having trouble.
The texture/material that I want to attach is wood panelling from the 70’s. I cannot find an existing texture and I am not really sure how to make one to use.
Any help will be most welcome.

there are a million images you can access online, simply search for what you want and copy it to the color channel of your materials.
