The Hands Behind Loewe's Puzzle Bag

The workshop sits on the fourth floor of Loewe's Madrid atelier, where the air smells faintly of vegetable-tanned leather and machine oil. Luz Fernández holds a single piece of calfskin against the light, checking for scars. She has done this for eleven years. The hide will become part of a Puzzle bag—specifically, the central panel that folds into the structure's signature geometric collapse. If the leather is too stiff, the bag won't close. Too soft, and it loses its shape by the second carrying. Fernández can tell the difference by touch.

She is one of seven artisans who work exclusively on the Puzzle, Loewe's most technically demanding piece since Jonathan Anderson took over as creative director in 2013. The bag requires forty separate panels, each cut and skived to a different thickness, then assembled without visible stitching on the exterior. It looks like an accident of geometry. It is not.

Training Ground

Fernández came to Loewe through the Escuela de Artesanos, the in-house training programme Anderson expanded in 2014. She had worked in a small leather goods workshop in Toledo, making document cases and portfolios. Solid work, but repetitive. The Escuela offered something else: eighteen months of instruction in Loewe's specific techniques, taught by master craftsmen who had been with the house since the 1980s.

The first three months were dedicated to skiving—the process of thinning leather edges so they can be folded or laminated without bulk. Fernández skived hundreds of practice panels, most of them binned. The angle of the blade matters. So does the pressure. Push too hard and you cut through; too light and the edge remains thick. By the end of the programme, she could skive a panel to half a millimetre without checking the caliper.

Her trainer was Vicente Sánchez, who joined Loewe in 1987 and now oversees the Puzzle production line. Sánchez does not use the word 'artisan' lightly. In a 2019 interview with El País, he said the term had been cheapened by marketing. What he looks for in a trainee is not passion or creativity—those are pleasant but secondary—but patience and a tolerance for repetition. The Puzzle bag takes sixteen hours to complete. Most of that time is preparation.

The Puzzle's Architecture

Anderson's brief for the Puzzle, developed with Sánchez in 2014, was deceptively simple: a bag that could collapse flat and still hold its structure when filled. The solution required a new approach to panelling. Traditional bags are built around a rigid frame or a single piece of leather that is shaped and stitched. The Puzzle uses neither. Instead, it is constructed from interlocking geometric panels, each one cut and folded so that the bag compresses without creasing.

The key is in the skiving. Each panel is thinned along its edges to different degrees, allowing them to overlap and fold in a specific sequence. The central panel, which Fernández prepares, must be skived to 0.4 millimetres on three sides and left at full thickness on the fourth. If the measurements are off by even a tenth of a millimetre, the bag will not fold correctly.

Sánchez developed the skiving template over six months of prototyping. He and Anderson went through forty-three iterations before settling on the final pattern. The early versions either collapsed too easily or remained stiff. The breakthrough came when Sánchez suggested varying the skiving depth within a single panel, creating a gradient of flexibility. It is a technique borrowed from bookbinding, where leather spines are thinned progressively to allow smooth opening.

Assembly Line

Once Fernández has prepared the panels, they move to Javier Ruiz, who handles the lamination. The Puzzle's interior is lined with suede, which must be glued to the calfskin panels before assembly. Ruiz uses a water-based adhesive applied in a thin, even layer. Too much glue and the leather stiffens; too little and the lining detaches after a few months of use. He works with a small roller, applying pressure in overlapping strokes. The panels are then pressed for twelve hours under weight.

Ruiz trained as a bookbinder before joining Loewe in 2016. He was drawn to the house specifically because of the Puzzle, which he had seen in a shop window and assumed was machine-made. When he learned it was hand-assembled, he applied to the Escuela. His background in bookbinding made him a natural fit for the lamination process, which requires the same attention to adhesive distribution and drying time.

After lamination, the panels go to Ana Morales, who handles the stitching. The Puzzle is unusual in that most of its seams are internal, hidden between the laminated layers. Morales stitches these seams by hand, using a saddle stitch that locks each thread in place. The stitching is invisible from the outside, but it holds the entire structure together. A single weak seam and the bag will begin to separate at the stress points—usually the top handles or the side panels.

Morales has been with Loewe since 2008, longer than anyone else on the Puzzle line. She remembers when Anderson first arrived and began pulling apart the archive, looking for techniques that had been abandoned. The hidden seam construction was one of them, originally used in Loewe's rigid travel cases from the 1920s. Anderson wanted to revive it for the Puzzle, but the technique had not been taught in the atelier for decades. Morales spent two months working with Sánchez to reconstruct the process from archival samples.

What Comes Next

The Puzzle has been in continuous production for a decade, with new colourways and sizes added each season. Fernández now trains incoming artisans, walking them through the skiving process she learned from Sánchez. The programme has expanded to include other Loewe signatures—the Flamenco bag, the Hammock—but the Puzzle remains the most demanding.

Sánchez is fifty-seven. He has no plans to retire, but the question of succession is present. Loewe has begun cross-training artisans so that each one can handle multiple stages of production. Fernández can now laminate panels as well as prepare them. Ruiz is learning to stitch. The goal is not interchangeability—each artisan still has a primary role—but continuity. If someone leaves, the line does not stop.

Anderson has said in interviews that the Escuela is not about preserving tradition for its own sake. It is about maintaining a level of craft that cannot be automated. The Puzzle could, in theory, be machine-assembled. The panels could be die-cut and laminated by press. But the result would not fold the same way. The hand-skived edges create a subtle variation in thickness that allows the bag to collapse naturally, following the user's movements rather than fighting them. A machine cannot replicate that variation.

Fernández is now working on a new prototype, a larger version of the Puzzle intended for travel. The dimensions are different, which means the skiving template must be recalculated. She and Sánchez have been testing panels for three weeks, adjusting the gradient until the bag folds correctly. It is the same process she went through as a trainee, but faster now. She knows what to look for.

The workshop is quiet in the afternoons, after the morning's cutting is done. Fernández works through a stack of panels, checking each one against the light. Some will be rejected. Most will move on to Ruiz, then Morales, then out into the world. Sixteen hours of work, compressed into a shape that fits under an arm. She does not think about the buyer. She thinks about the fold.
