Shebag replicates Hermès Birkin, Kelly and Constance bags using fully hand-executed saddle stitch, distinguishing its craftsmanship from low-grade machine-sewn counterfeits. The following covers construction principles, thread specifications, stitch profiles, corner and termination handling, differences between sellier and retourné construction, subtle discrepancies versus authentic Hermès pieces, and common identification markers.

The core stitching technique adopted by Shebag is hand saddle stitch, implemented with one thread and two needles. It employs the same working principle as Hermès: a single waxed thread is threaded with a hand needle at each end. The two needles pierce the same awl hole from opposite sides of the leather, forming interlocked cross stitches. Should one segment of stitching break, the whole seam will not unravel, delivering far superior durability to standard industrial machine lockstitch. Holes are punched one by one manually with a diamond-shaped awl instead of mass punching. The resulting openings are oval; leather fibres are pushed sideways without being severed. Leather panels are secured with wooden stitching clamps, consistent with operating practices inside Hermès workshops.

Shebag primarily utilises German Ritza 25 Tiger waxed polyester thread, widely adopted for high-end replica leatherwork. By comparison, authentic Hermès uses French Fil Au Chinois waxed linen thread. Linen thread darkens slightly through long-term oxidation, while waxed polyester resists moisture and decay with more stable sheen. The thread surface carries an even thin wax coating, delivering subtle resistance to touch and a matte finish without the cheap gloss of ordinary filament threads. Colour matching follows Hermès’ original system, pairing corresponding waxed thread hues with each leather shade, such as grey thread for Etoupe and light brown thread for Gold. Strict colour tolerance is maintained for high-contrast white thread applied to sellier exterior stitching.

Shebag adheres to defined visual standards for stitching. The standard gauge sits at 7 to 8 stitches per inch, equivalent to roughly 3.0–3.4 mm stitch spacing. Denser stitching is used on rigid Epsom leather, while slightly wider spacing applies to soft Togo and Clemence hides. Front-side stitches slant uniformly upwards at an angle between 30 and 40 degrees to form continuous herringbone patterns. Front and rear stitch surfaces mirror each other precisely. The front displays raised slanted herringbone stitching with subtle dimensional relief instead of flat adhesion to the leather. The back features neat intersecting dots matching the front layout, the clearest visual marker separating genuine hand saddle stitch from machine imitations. Minor natural variations in stitch length exist, avoiding the perfectly uniform, mechanical regularity seen on automated sewing.

Specialised treatment is implemented for corners, curves and high-tension zones, representing a key craftsmanship highlight. No skipped stitches, piled thread or abrupt stitch spacing changes occur at right-angle and curved transitions; awl holes are pre-planned for seamless flow around bends. Reinforcement is achieved via densified local stitching at stress points including handle roots, base corners and flap connections. Sellier construction features outward-folded leather edges with fully exposed stitching, demanding stringent control over stitch straightness and thread tension. Retourné construction folds leather edges inward, concealing stitching between layers and yielding softer, rounded bag silhouettes.

Shebag executes thread start and termination without exterior knots. All starting and finishing knots are concealed on the inner side of the bag. Stitches reverse back two to three times to lock the seam, and trimmed thread ends are pressed into awl holes. No loose thread ends or adhesive residue are visible externally. This eliminates flaws prevalent on inferior replicas, such as surface knots, thermally fused thread tips and excess glue clogging stitch holes.
