Need some advice with curtain material

Hi, i’m pretty new to interior modelling, this is my second (bigger) work in blender and i need some advice with curtain material.




heres a test render, 3d view and node setup.
I would like them a little bit less transparent but still keep the translucency, but i cant figure it out…

Thanks for any help guys^

I made this tiling grayscale texture for this purpose…reports vary on it’s effectiveness.
