Étienne’s production relies on a collection of meticulously restored vintage sewing machines, each chosen for its unique stitch characteristics that contribute to the historically accurate construction of every garment. These machines, some dating back nearly a century, were originally designed for industrial and workwear applications, ensuring durability and precision that modern equipment often cannot replicate.One of the key machines in the atelier is the Singer 31K20, a straight-stitch industrial sewing machine with an oscillating shuttle mechanism. This design provides a smooth yet slightly irregular stitch, reminiscent of early workwear construction. Its ability to handle heavyweight fabrics makes it ideal for topstitching denim with an authentic vintage appearance.
