Thank you - Max -. 'parchment textures' was the words I'm looking for (I'm not a native English speaker).

The problem with free google downloads is the size of it.
If I want to draw a map of size 42 by 29,7 cm (A3) or bigger, the download picture lacks the crisp I need for print.

Also, I found a useful tutorial right from this forum:
