The Penn Dutch/Amish Hex sings have nothing to do with superstition.
About 300 years ago, groups of peasant farmers from the Rhine region of Germany migrated to southeastern Pennsylvania. These settlers came to take advantage of religious freedom being offered by William Penn. They included settlers of plain dress -Amish and Mennonites - and others of more "worldly" or "fancy" dress - Lutherans and other Reformed groups. Over time, these settlers became known as "Pennsylvania Dutch".
Like
other immigrants, they brought their old world language, dress, traditions and art to their new home. Mystical bird and floral designs graced their birth and marriage certificates, family Bibles, quilts, and some furniture. The "fancy" farmers also decorated their large German style bank barns with colorful geometric patterns. Six-pointed star designs were very popular. The German word for six, "sechs", sounded like hex to their English-speaking neighbors. In time these "hex" patterns became commonly called hex signs. This custom persists today.
These bright, colorful designs had meanings or legends. Families selected a hex sign based on color, design and its meaning. Some of the more popular symbols included: hearts for love, birds (called distelfinks) for luck and happiness, tulips for faith, and stars for good luck. The colors used for painting were also carefully chosen because of their added meaning. Blue conve
yed protection, white purity, green abundance and red strong emotion. The hex symbols were individually hand painted for many years. This approach, naturally very time consuming, limited hex sign use and enjoyment even in the Dutch Country.
