A research project was undertaken with the goal of developing a rug repair technique that would provide visual and aesthetic continuity, respect for the original materials, structural soundness, and reversibility. Rug restorers, dealers, and collectors were interviewed about traditional weaving techniques, e.g., kashmiring, darning, plugging, or reweaving. The conservation literature was researched to see which treatments might have positive visual effects without potentially causing further damage. The technique adopted for this case study is called passive fill because a fabric patch attached behind a newly woven plug, acts as the consolidating element. There was minimum handling of the piece while work progressed because most work was done with the rug on the loom.
