Vintage Zig-Zag Afghan Blanket

Classic vintage Zig-Zag knit blanket with zig-zag edge. Approx 48x80". Bold stripes -- bright orange offset by cream, tan, and brown. To my lay eyes it appears to be acrylic and handmade. There is some slight discoloration on the cream-colored corner. Last pic shows the discoloration, I'd argue it's not really noticable in everyday use. I've machine washed in cold water and tumble dried on low. ***Comes from a dog-friendly home!
