Feathers are a feather-shaped embroidered finish on the top of a quilt. Feathers are essentially made from a spine around which teardrop or semi-circular ridges are sewn. Feathers can express the particular style or skill of the quilter as they are often sewn by hand using a hoop, needle, and thread. Feathers can also be sewn using a long-armed machine or with free-motion quilting supplies. Feathers are used to add texture to the design of a finished quilt. The design of feathers can vary from simple flourishes to more intricate plumes depending on the preference and skill of the quilter.
