HEATNBOND Sew‑In Non‑Woven Interfacing adds firm, flexible body for craft construction and select garment areas without fusing. The bolt measures 20" × 10 yd (50.8 cm × 9.1 m) and can be stitched in for stability where heat‑sensitive fabrics or dimensional builds are used. Great for wallets, bags, and structured elements; choose sew‑in when you prefer needle‑based control over adhesive bonding. Follow manufacturer guidance: prewash without softener and test on scraps before fusing.
