FAIRFIELD Poly-Fil® Premium Fiber Fill is a polyester stuffing designed for big craft builds and décor projects that need dependable loft. This 10 lb (4.54 kg) box supports high-volume stuffing for oversized pillows, large plush, or batching multiple items in one session. Pack the fiber in layers to avoid hollow spots, and after washing a finished piece, reshape and redistribute the fill so the surface stays smooth.
