Vintage Crazy Stocking Patchwork Mod Lined Handmade OOAK Christmas Prop

Very unique stocking! Measures approx 15” long from top to heel. Cotton type fabric and red flannel lined. Smoke free, no rips. There is a shadowy discoloring on the pink heel fabric ...see the last two pics (front and back). Not sure if this is under the fabric or if it is discoloration. This is not quilted.
