Linen procedural material for dummies

Hi guys,
i’m back to learning blender and i reached a point where figuring out Nodes and how to make my own procedural texture is a must.
I work with fabrics, and all the materials seem just a little bit wrong when comes to light weight clothing. So i’m trying to get started at procedural materials and making it right.

This is where i went so far. A very simplied version of where i started.!
My biggest struggle has been the bump and displacement which should be more or less random. Also i should have a few lumps and impurities within the plot.

Hopping to get some critics and directions.
