Happy Baba Marta Day! This is a Bulgarian holiday to celebrate Grandmother Martha, the bringer of spring. Observers exchange and wear red and white tassels, called Martenitsas to guard against evil. Once the wearer has seen a stork or blossoming tree, they remove the Martenitsa and hang it from the tree.

Back in my youth, one of the sillier worksheets we used to get in math class was the number comparison worksheet. the teacher used to explain the greater-than and less-than symbols as, “the alligator easts the larger number.” That got me thinking that it would be a fun way to theme a Futoshiki puzzle.
