Piping & Welting Cord for Sewing

Start with cord diameter, because that decides everything else. Thin 1/8"-3/16" piping defines apparel seams, baby quilts, and small accent pillows; 1/4" is the workhorse for throw pillows, cushion covers, and slipcovers; 5/16"-1/2" welt cord gives sofa cushions and headboards a structured edge. Decide between ready-made piping (uniform, stocked in solid colors, fast) and cord plus bias tape when you need a print-matched custom finish. Cotton cord presses crisply but can shrink, so pre-wash anything washable; polyester or foam welt cord resists shrinking and bends around tight curves for round cushions. Expect roughly $3-$10 per yard for fabric-covered piping and $1-$4 per yard for plain cord; many independent makers cut to order and ship in 3-7 business days, with custom-fabric runs taking 1-2 weeks. Check the listed flange width so it fits your seam allowance.

Use the filters for cord size, material, and color, and the related searches to jump to upholstery welt, narrow apparel piping, or custom print-matched trim.
