To attach a
back patch for jacket, start by laying the jacket flat on a clean surface. Then, position the back patch in the desired location and secure it with pins or fabric tape to keep it in place. Next, carefully sew along the edges of the patch using a needle and strong thread. Be sure to sew through both the patch and the jacket to secure it properly. Once the patch is securely attached, remove the pins or fabric tape and trim any excess thread. Finally, gently press the back of the patch with an iron to ensure it is securely adhered to the jacket.
