A fixation device for fixation of soft tissue to bone with a body formed essentially of resorbable or non-resorbable yarns. The fixation device may be a knotted or a knotless construct. The fixation device is a soft, yarn-based whipping anchor which is formed by providing a suture eyelet, and passing a plurality of passes of yarns around the suture eyelet (forming a whipping twine), using the suture eyelet as a mandrel, to create a robust construct which may have geometrically-shaped features such as barbs. The eyelet and the twine may be made from resorbable material, non-resorbable material, or combination of resorbable and non-resorbable materials.
