Inspired by the wallpaper in 221b Baker Street in BBC’s Sherlock, smiley-face and all.
I made the black pattern with a liquid eyeliner and it was bloody difficult!
But practice makes perfect, right? 

I used colour nr. 24 from Tiger as base, a liquid eyeliner for the pattern. Depend nr. 35 for the smiley and e.l.f.’s Matte Finisher as topcoat!
