In our example, the original speedlace was connected at the ends with a fabric pulling patch. We will re-attach it in now, using the sewing machine.

Wrap the patch around the lace endings and place it onto the sewing machine. The open side (red circle) should point towards you.

Push lace endings against each other in the middle of the patch, so that there is no gap.

Sew along the middle of the patch with a single straight stitch. The goal is to sew through both laces at the same time, and "tack" everything in place for the next step.
