Close-up of autumn winter flannel tartan fabric

A close-up photograph of a vertical autumn/winter plaid fabric. The main subject is a flannel-textured woolen fabric covered with classic Scottish tartan woven from olive green, wine red, off-white, and dark gray, with a clear diagonal weave texture. In the center, the English text "Grey November, I've been down since July" is printed in white handwriting, centered. The overall tone is retro and low-saturation, with soft and even lighting and no strong shadows, presenting a melancholic yet warm artistic atmosphere, like an emotional retro mood poster.
