Self Edge, the cult denim shop, has vintage Union Special sewing machines in order to hem your jeans with a chain stitch. Coveted by denim heads, the special stitching promotes a "roping" effect in the jeans by slightly twisting the hem. Owner Kiya Babzani also stocked the shop with a 1950s Singer darning machine, capable of repairing your jeans without the use of patches. Darning was the standard practice of denim repair until the 1960s, and works by weaving threads together to essentially create new fabric where none previously existed—turning out a considerably more streamlined look.
