Introduction
High-stretch sports clothing, such as fitness or running leggings, have flat seams ("flatlock" seams) that can get damaged over time. These can be repaired with a sewing machine which has a Zig-Zag stitching function, in order to keep the seam's elasticity. In this guide we'll show you how!
Tools
-
-
Locate the damage on your item.
-
This is often in a high-stretch area of the flatlock stitching.
-
-
-
Cut away and broken thread in the area to repair.
-
Adjust the sewing machine to the Zig-Zag stitch setting, and with the correct width (it should match your flatlock stitching width).
-
-
-
Place the garment underneath the sewing machine and depress the foot.
-
Carefully stitch all along the broken seam.
-
Take care: thin and stretchy fabric can be hard to work with. Take your time!
