Poly-Fil Basic Pillow Insert — 12" x 16"
The Poly-Fil Basic Pillow Insert is the finishing component for quilted pillow covers and cushion projects — a ready-made polyester fiber form in the standard 12" x 16" lumbar/rectangular size. For quilters making pillow covers, cushion fronts, and decorative throw pillows, having the right insert on hand completes the project without a separate trip to a home goods store. Poly-Fil's cluster fiber construction delivers lofty, resilient fill that holds its shape through regular use and washing. The 18" square insert covers the classic throw size, with Perfect Loft loose fill for custom shapes.
Size: 12" x 16" | Fill: Polyester cluster fiber
Frequently Asked Questions
What cover size fits a 12" x 16" insert?
Sew the cover 1–2" smaller than the insert — an 11"x15" finished cover gives the plump, filled look designers want; covers cut to exact insert size look deflated.
What projects suit the lumbar shape?
Pieced-strip and panel pillow fronts — the rectangle showcases horizontal quilt blocks, mini-quilt rows, and embroidered panels better than a square.
Can the insert be washed?
Yes — machine wash and fluff in the dryer; the cluster fibre recovers its loft, so covers and inserts both stay refreshable.
