Make a difuse shader pass the light through

Hey, im making some interior and i have this problem: there’s a black curtain on the window. Its made out of defuse BSDF + transparent mixed with mix shader and i used image texture as factor, so it looks like it has mini holes in it.
It looks transparent enough and i cant make it more, but i want it to pass more light through, how do i do that?

Mix diffuse with translucent before mixing that with transparent.

Change the mix value or change the image texture to have thinner lines.
