The 1/4 Silk Black is a whisper of diffusion in a fabric that refuses to bounce, softening a source just slightly while the black weave keeps stray light from lifting the room. It is the rag for taking the sting out of a backlight or edging without changing the exposure conversation, exactly the kind of subtle tool DPs build looks around. LA Rag House sews them in the USA from the 4x4 slip-on up through the 20x20. Small correction, big difference.
