End state: when you cut the three-piece suit, every technique in it is already familiar.
The suit is difficult because it is large, exacting, and long, not because it contains skills you have never performed before.

Stage 0
The Bench
Approx. 5–8 hours
Purpose: Make basic hand-sewing setup physically routine before technique practice begins.
Done when: You can sew continuously for 15 minutes with the thimble without repeatedly abandoning it, and you can prepare a new thread without looking up the process.
Stage notes
Stage 1
Stitch Book
Approx. 15–25 hours
Purpose: Build the small vocabulary of stitches that tailoring repeatedly uses.
Done when: The second 15 cm backstitch seam stays roughly within 2 mm of its marked line, lies flat after pressing, has no loose loops or obvious gaps, and does not open under a firm two-handed pull. You can also identify the core stitches from unlabeled samples and state their purpose.
Stage notes
Stage 2
Cloth and Iron
Approx. 10–15 hours
Purpose: Treat pressing as construction and shaping, not cleanup.
Done when: You have one labeled sample book page showing seam construction plus pressing, and one wool sample that visibly holds a deliberate curved shape after cooling.
Stage notes
Stage 3
Repair and Alteration Shop
Approx. 20–35 hours
Purpose: Learn to diagnose fit and construction by changing existing clothes.
Done when: Three garments are wearable after alteration, including at least one shirt and one pair of trousers, and your notebook states what symptom you saw, what seam or component controlled it, what you changed, and what the result was.
Stage notes
Stage 4
EDC Bag I and II
Approx. 20–35 hours
Purpose: Get lots of construction mileage without fitting problems, while practicing iteration.
Done when: Bag II survives a week of real use without structural failure, and your notebook clearly states at least three lessons carried from Bag I into Bag II.
Stage notes
Stage 5
Trouser and Waistcoat Component Board
Approx. 25–40 hours
Purpose: Move difficult operations out of garments and onto scrap.
Done when: You have two functional button flies, two clean welt/jetted pockets, four functional hand buttonholes, one waistband sample, and a labeled reinforcement board. The second attempts must be completed from your notes rather than a live tutorial.
Stage notes
Cabrera: Start using the trouser and vest sections here as the construction authority for component order and terminology.
Stage 6
Trousers I
Approx. 30–50 hours
Purpose: Complete a full lower-body tailored garment with a button fly in inexpensive cloth.
Done when: The trousers survive three days of ordinary wear; the fly lies flat and functions; pockets function; no seam opens; and your notebook contains specific fit defects rather than a general impression.
Stage notes
Cabrera: Follow Cabrera's trouser construction sequence unless you have a documented reason to deviate.
Stage 7
Waistcoat I
Approx. 25–40 hours
Purpose: Enter tailored upper-body fitting without sleeves and complex shoulder structure.
Done when: The waistcoat closes without strain or major gaping, fronts hang evenly, pockets and buttonholes function, and you have revised the pattern from actual wear.
Stage notes
Cabrera: Use the vest/waistcoat construction section as the main sequence.
Stage 8
Cutting, Pattern, and Fit Apprenticeship
Approx. 30–45 hours
Purpose: Turn successful garments into controlled, repeatable patterns for your own body.
Done when: You possess stable, numbered trouser and waistcoat master patterns corrected through toile fitting, and you can explain what each major correction was intended to change.
Stage notes
Stage 9
Trousers II and Waistcoat II
Approx. 50–70 hours
Purpose: Repeat familiar garment types in wool and confirm that your patterns are stable.
Done when: Both garments survive normal wear, fit acceptably, and the final pattern revisions are small refinements rather than rescue operations.
Stage notes
Stage 10
Simple Jacket
Approx. 35–55 hours
Purpose: Learn jacket geometry before adding full bespoke coat structure.
Done when: The collar sits against the neck reasonably well, sleeves hang without major diagonal twist, sleeve heads have no obvious accidental pleats, pockets work, and the jacket survives wear.
Stage notes
Stage 11
Coatmaker's Sample Board
Approx. 40–70 hours
Purpose: Learn every difficult bespoke-jacket operation before combining them in a coat.
Done when: Every major jacket component exists as a labeled physical sample, and the second welt pocket, second lapel/canvas sample, and repeat sleeve-related sample can be completed from your notes.
Stage notes
Cabrera: This is where the coat/jacket chapters become the main construction reference.
Stage 12
Jacket I: Apprentice Coat
Approx. 70–110 hours
Purpose: Combine the already-practiced coatmaking operations in inexpensive real wool.
Done when: You have completed a fully tailored wool jacket, worn it five times, documented its fit, and revised the paper pattern from actual use.
Stage notes
Stage 13
Permission to Cut the Suit
Entry examination
Purpose: The suit does not begin until every required technique has already been demonstrated.
Done when: Every box above is checked. Any failed item becomes a sample exercise or revision project. No suit cloth is cut before this page is complete.
Exam notes
Stage 14
The Three-Piece Suit
Likely 100+ hours by hand
Purpose: Execute familiar skills at larger scale, with stricter consistency and planning.
Done when: You have a wearable three-piece suit, every component has survived real wear, and the final notebook entry explains what you would carry forward into the next suit.
