The fabric flowers were created by a group of yarnbombers in the village, and helpers, and stretch about 1.6 miles. Children at the village school and at the under-5s group also played their part, and there is a display outside the school.
There are poppies - mainly red but also white, blue, purple and black - decorating walls, railings, gates, the village hall and school, telephone box, and a life-sized figure of a soldier outside the village hall.
People from around the world with connections to Hackness have sent poppies and money.
