Project Zomboid Tailoring Guide: Repair, Patch & Level Up (Build 42.19)

Build 42.19 · Patch protection, full restore at Tailoring 8+, XP tables, and skill-book multipliers 3/5/8/12/16

Quick answer Use Tailoring to patch holes, add padding, fully restore matching fabric at skill 8+, and plan XP with the correct skill-book volume for each level band. Skill books multiply by 3 / 5 / 8 / 12 / 16 (not a flat 3× on every volume).
Key facts players often get wrong Patch defense scales with Tailoring: roughly fabric max × max(1, level) ÷ 10 (at least +1% when the fabric can grant defense). Full restore needs Tailoring 8+ and matching fabric. Remove-patch reclaim is only 10 + 5 × level% (60% at 10, never 100%). Add patch is always 2 XP; remove gives 2 XP only when the fabric returns. Shorten recipes and Pick Thread grant no Tailoring XP.

Why Tailoring matters

Clothes wear out and get holes. A hole on a covered body part removes that part’s protection until you fix it. Higher Tailoring makes patches stronger, improves reclaim chance when you remove a patch, and unlocks full hole restoration with matching fabric at level 8+.

Bulletproof vests and many military pieces still have strong base armor, but they are not a substitute for keeping holes closed on everyday layers.

Tools and materials

Needle icon Needle Required for patches; uses condition
Thread icon Thread About 20 uses per full spool
Scissors icon Scissors Cut denim/leather; weapon durability
Ripped Sheets icon Ripped Sheets Cotton fabric for patches
Denim Strips icon Denim Strips Cut denim clothes
Leather Strips icon Leather Strips Best patch defense
Stone Awl icon Stone Awl Knapping; Pick Thread tool option
Item Role in Build 42.19 Notes
Needle / bone / forged needles Required to add or remove patches Not infinite: base Needle uses condition; keep spares
Thread Consumed when adding a patch Full spool ≈ 20 patches; loot or craft (see below)
Ripped Sheets / Denim / Leather strips One strip per patch Dirty strips must be cleaned before use as fabric
Scissors Rip/cut denim and leather clothing Ordinary scissors have condition and can break
Tailoring skill books (5 vols) XP multipliers 3 / 5 / 8 / 12 / 16 Each volume covers two skill levels (1–2, 3–4, … 9–10)

For thread sources (loot, Pick Thread, spinning wheel), see How to Get Thread. Ripping cotton clothes yields sheets—not free Thread.

How to inspect and patch

  1. Have a needle, thread, and fabric strips in inventory.
  2. Right-click clothing → Inspect to open the garment UI (body parts, holes, scratch/bite/bullet columns).
  3. Right-click a body part with a hole → Patch hole, or a clean part → Add padding.
  4. Choose Ripped Sheets, Denim Strips, or Leather Strips. The tooltip shows live +scratch / +bite from your current Tailoring.
  5. To grind XP: add a patch, then remove it (reclaim chance depends on skill). Removing always needs a needle; reclaim is not guaranteed.
Inspect clothing window showing body-part coverage and defense columns
Inspect view: per-part coverage and defense. Use it before patching so you know which hole matters.
Items you cannot treat as normal fabric clothing Pieces without a fabric type (many helmets, some hard armor, certain shoes) cannot take fabric patches. Once destroyed, replace them.

Patch defense (Build 42.19)

When a patch is applied (hole or padding), defense uses the fabric’s max values and your Tailoring skill:

  • Effective level = max(1, Tailoring skill) — level 0 and 1 use the same defense.
  • Scratch bonus = floor of (fabric max scratch × effective level ÷ 10), at least +1% if the fabric has any scratch max.
  • Bite bonus = 0 if the fabric has no bite max; otherwise floor of (fabric max bite × effective level ÷ 10), at least +1%.
Fabric Item Max scratch / bite at level 10 Level 1 (and 0) Level 5 Level 10
Cotton Ripped Sheets 5 / 0 +1% / +0% +2% / +0% +5% / +0%
Denim Denim Strips 10 / 5 +1% / +1% +5% / +2% +10% / +5%
Leather Leather Strips 20 / 10 +2% / +1% +10% / +5% +20% / +10%

These bonuses apply per patched body part on that clothing item. Patch hole and add padding share the same patch defense math when a patch is created. They are not two different percentage tables.

Full restore (holes only)

If all of the following are true, the action fully restores the hole instead of leaving a fabric patch:

  • There is a hole on that part
  • Your Tailoring is greater than 7 (level 8, 9, or 10)
  • The fabric matches the clothing (Cotton on cotton, Denim on denim, Leather on leather)

Full restore removes the hole and returns condition for that hole—it does not add the padding-style defense patch. For pure armor stacking on intact clothes, use Add padding with the best fabric you can spare.

Clothing with holes and patch options in the inspect UI
Holes vs padding: same inspect UI; full restore only appears when skill and fabric match.

Example base clothing (not patch values)

Item Fabric Scratch Bite Notes
T-shirt Cotton 0 0 Light layer; patches matter more
Denim shirt Denim 15 7 Solid mid-tier shirt
Leather jacket Leather 40 20 Strong everyday jacket
Army bullet vest — 55 30 Also Bullet 100; not fabric-patchable

XP, reclaim, and skill books

Action Base Tailoring XP Details
Add patch (hole or padding) 2 Always; consumes 1 fabric strip + 1 thread use
Remove patch 2 only if fabric returns Reclaim chance = 10 + 5 × Tailoring% (level 0 → 10%, level 10 → 60%)
Pick Thread 0 (no Tailoring XP) Tailoring 1; 1× Ripped Sheets or Denim Strips + needle/tweezers/awl → 1 Thread use
Shorten skirt/sleeves/socks/trousers 0 (no Tailoring XP) Utility / materials only—not an XP grind
Many sew/knit/armor crafts Recipe-specific Large awards at higher Tailoring; good late-game XP
From → to Base XP needed Skill book volume Multiplier
0 → 150Vol 1 (levels 1–2)×3
1 → 2100Vol 1×3
2 → 3200Vol 2 (levels 3–4)×5
3 → 4500Vol 2×5
4 → 51000Vol 3 (levels 5–6)×8
5 → 62000Vol 3×8
6 → 73000Vol 4 (levels 7–8)×12
7 → 84000Vol 4×12
8 → 95000Vol 5 (levels 9–10)×16
9 → 106000Vol 5×16

Total base XP 0→10 = 21,850. With the correct book for every band, expected “raw” XP after multipliers is much lower, but remove-patch XP is probabilistic—plan thread and fabric with a margin.

Practical leveling route

  1. Read the Tailoring volume that matches your current band before grinding.
  2. Loot Thread early; Pick Thread at Tailoring 1 turns surplus sheets/denim into one thread use each (inefficient vs loot, but infinite).
  3. Main grind: add patch (+2 XP) then remove. Expected XP per cycle ≈ 2 + 2 × reclaimChance before book multipliers.
  4. Keep leather for real armor; grind mostly with ripped sheets once you can feed thread.
  5. At 8+, fully restore matching-fabric holes on good clothes instead of stacking weak cotton on denim/leather pieces.

Topic Older B41 habits Build 42.19
Thread supply Often treated as ripping byproduct Loot spools, Pick Thread, sinew, spinning wheel; ripping is for fabric strips
Crafting Mostly repair/padding Large Tailoring craft tree (clothes, packs, knit, armor assembly) with recipe XP
