The elements in the Assomption sash pattern are the central arrow flanked by lightnings.
The lightnings are lozenge shapes connected to the next lozenge by a thin line.
The ladies of Assomption, Quebec, wove sashes for the Fur Trade companies in the early 1800s. They standardized the pattern and color sequence: a red arrow ( the heart of the sash) in the middle, flanked by lightning patterns of white, dark blue, pale blue, red, yellow, and green. These are the required colors and run down the center of the sash. Wide sashes have more lightnings. These wider sashes sometimes repeat the required colors, sometimes varying the colors.
