Fabric Wallpaper - Procedural Material

Since winter is coming and everything here is wet, hidden in darkness and hard to scan, I went back into procedural materials. I picked fancy eastern European fabric wallpaper as target. Especially, this kind of surface is pretty hard to scan using photogrammetry and can be captured efficiently only by using photometric stereo technique or by being procedurally generated.
As I didn't have anything like that to scan nearby, just last option made sense :).
I created it using Substance Designer in a couple of hours. From efficiency point of view, the 'pattern' part was a handicap and this is the part I am going to improve with next material. Now it is definitely over complicated and might be a big problem with more complex and demanding shapes.
