I'm 50 and still use the one I had as a girl: red flannel, white fold over with my name machine embroidered in green. At some long-past Christmas, I had a few too many chocolates and upchucked on it. When my mother laundered it, the red bled into the white, so now the fold over is pink. Unfortunately, Santa doesn't fill it -- so I put my own favorite candies and little trinkets in it.
I bought my kids' stockings. They are needlepointed, one with Santa, the other with a tree, and their names machine embroidered in white on the red velvet top. They look big but because of the construction are quite flat and don't hold much -- less work for Santa.
My father still has his from childhood. He was born in 1928 and his stocking looks more like a knee sock than the L-shaped flat stockings of later years. It's plain red with a white cuff and his name embroidered in his mother's rather shaky stitching.
