Matte, glossy with high roughness or matte/glossy translucent? (although I doubt it, I find the translucent mat very prone to noise, and your image is very clean).
Well, yes, it's simply a matte translucent material with 0.45 reflection and 0.4 transmission. I've also added a slightest bump to it and a texture to modulate transmission channel (to simulate quilting seams), but made them so light as making them invisible.

I can't say blinds contributed to the noise too much, the hardest part i think was where they are stacked together at the right of the plant.

Just name them!

Most materials here are very simple. Plant leaves took me awhile to make right, but basically these too are just glossy translucent
