A martenitsa, worn on the shapely wrist of a Bulgarian friend of mine. Like most Bulgarians, she’s been wearing it since March 1, and will put it on the first blooming tree she sees:
Wikipedia drops knowledge on Martenitsas:
This is an old pagan tradition and remains almost unchanged today. … Many people wear more than one martenitsa. They receive them as presents from relatives, close friends and colleagues. Martenitsa is usually worn pinned on the clothes, near the collar, or tied around the wrist. The tradition calls for wearing the martenitsa until the person sees a stork or a blooming flower.
So, the next time you’re walking through a park in Germany, look closely at the trees that tend to bloom early. If you see martenitsa on them (and you will, if you look), you’ll know there are Bulgarians in your midst. It’s a nice feeling!
