No piece we make is drafted from nothing. Each begins as a block — a plain, shapeless, perfectly fitted master pattern that exists only to be departed from.
In the pattern room there is a shelf of card shapes, each hanging from a hook, none of them beautiful. They have no lace, no shaping beyond what a body requires, no design at all. These are the blocks — sometimes called slopers — and they are the most valuable objects the house owns. Every finished piece in the collection is a descendant of one of them, and none of them will ever be made as a garment.
What a block is
A block is a master pattern that fits a specific set of measurements with no ease beyond what is functionally necessary and no design content whatsoever. It is a record of a shape, nothing more. The cradle block describes the frame that sits under and around the cups. The cup block describes a volume and the seams that produce it. The brief block describes the relationship between waist, hip and leg line. The slip block describes a torso from shoulder to hip. Each was arrived at through fitting, over months, and each is corrected whenever the fitting room proves it wrong.
The point of a block is that it removes the hardest question from every subsequent job. When a designer asks for a new soft-cup piece, nobody starts by wondering what shape a body is. That question has been answered, permanently, and what remains is only the design — where the seams go, where the lace falls, how high the wing rises. This is why a house with good blocks moves quickly and a house without them makes the same mistakes over and over in different colours.
How a block is made
Slowly, and it is never made only once. The first version is drafted or draped, cut in calico, and fitted. The corrections are transferred to card and it is fitted again. This continues until the toile shows no drag lines, no gaping, no pressure, and hangs correctly with the wearer standing, sitting and leaning. It might take six iterations. Once it is right, the card is trued: every curve faired, every pair of seam lines measured against its partner so the lengths agree exactly, every notch and balance point marked and labelled. A block that has not been trued will pass its errors quietly to every garment ever built on it.
“A block is the least interesting object in the room and the reason everything else in it is possible.”

Working from a block
Design begins by tracing the block onto fresh paper and then departing from it, deliberately and one decision at a time. The traced copy is what gets cut, slashed, rotated and re-drawn; the block itself is never marked. A vertical cup seam is moved. A neckline is lowered. A dart is rotated into a seam. Ease is added at the upper cup because this piece is to be worn under a soft knit. At every step the original shape remains available for comparison, which means a patternmaker can always tell whether a fit problem came from the design she just made or from the block underneath it — a diagnostic luxury that is impossible when a pattern is drafted from scratch each time.
- Never cut the block itself. Trace it, and cut the tracing.
- Label every block with the measurements it represents and the date it was last corrected.
- True all opposing seam lengths before a block is put into service; an untrued block infects everything downstream.
- Re-fit blocks periodically. Bodies in a client list change, and so do the materials the house is buying.
- Keep the superseded versions. A correction that once seemed obvious is sometimes an error you will want to trace back.
The block as memory
For a made-to-measure client, her block is her. It stays in the pattern room with her name on it, and when she commissions a second piece three years later, the work does not begin from measurements again — it begins from her shape, verified at a short fitting and adjusted where life has changed it. The card is a physical record of an hour somebody spent understanding a particular body, and it means the second garment is better than the first, and the fourth better still. That accumulation is the real argument for working this way, and it cannot be bought, only kept.
