A parzenica is a heart-shaped traditional handicraft pattern and decorative folk art of the Goral people, who live in the mountainous region of southern Poland.
[1] The origin of the term is unclear, it is possibly related to old-Polish verbs parznąć and parznić meaning to make some object filthy.
[3] Initially the name also applied to various other objects popular in everyday life of the Goral people, including wooden forms used in cheese production and heart-shaped motifs used in wood carving.
The "Knightly knot" is a decorative motif laid in three-loop of string, characteristic for highlander's male costume,[6][5] often used as base for parzenica.
Using woollen yarn allowed the parzenica to become more colourful and eventually it became a stand-alone trouser ornamentation, developed by talented tailors and embroiderers.
