If you think you need a steady hand to apply eyeliner, then try drawing straight seams up the backs of your legs! During WW2 when stockings were in short supply women were encouraged to use liquid stockings instead, and to draw the seams using eyeliner (or to get a friend to do it for you!).
I particularly like the fact that there are lots of cats in this picture. My grandma said that they used gravy-browning as liquid stockings but there was always the issue of cats and dogs wanting to lick your legs because they smelled nice and meaty!
