Custom T-Shirt Silhouettes Pattern-Made to Order
Every silhouette gets its own pattern — drafted from scratch around the dimensions, not pulled off a stock block and decorated. A reference image or a handful of measurements is all it takes to kick off development.

ArtisanFabric Guide
Match GSM & Fiber to the Brand.
Three weight brackets cover 90% of t-shirt projects. Each fabric runs in single jersey — airy, drapey, breathable — or interlock, which adds density, opacity, and edge-curl resistance at roughly 20% higher GSM.
Lightweight Cotton
- Single jersey: breathable, drapey, ideal for screen-print and DTG
- Interlock option: denser, opaque, zero transparency under bright light
- Heathered appearance without dye; softens further with each wash
Midweight Cotton
- GOTS certified with full chain-of-custody documentation to farm level
- Ringspun for smoother, stronger yarn — pill-resistant after 30+ washes
- The sweet spot: substantial hand-feel without stiffness, prints on both sides stay opaque
Heavyweight Cotton
- Substantial, structured drape — oversized silhouettes hold their shape
- Combed for a cleaner surface; ideal for 3D embroidery and heavy plastisol prints
- Interlock option adds density and opacity — no show-through even on white tees
Decoration & Finish
Six Ways to Mark the Garment.
The right technique depends on the project — screen printing scales with volume, DTG handles photorealism at any quantity. The team matches technique to artwork complexity, fabric substrate, and per-unit cost target.
Screen Printing
Pantone-matched plastisol or water-based inks pushed through mesh screens onto the fabric — one screen per color. Bold, opaque, most economical at 100+ units.
3D Puff Embroidery
Raised dimensional embroidery with foam underlay beneath thread — up to 6mm puff height. Creates a bold, tactile logo that sits off the fabric surface.
Direct-to-Garment (DTG)
Inkjet printing directly onto fabric — CMYK + white underbase for dark fabrics. Full-color photorealistic prints, zero screen setup costs.
All-Over Sublimation
Dye bonds with polyester fibers at the molecular level — unlimited colors, edge-to-edge coverage. Zero hand feel, won't fade, crack, or peel.
Acid Wash / Enzyme Wash
Chemical or enzyme treatment that strips surface dye unevenly for a worn, vintage look. Each garment is unique — no two come out the same.
Garment Dye
The entire finished t-shirt is dyed after assembly — not cut from pre-dyed fabric. Produces a lived-in, heathered patina with softer seams and edges.
Have a design locked in — or starting with a napkin sketch?
Whether your design is locked or you are working off a napkin sketch, a sourcing lead gets back to you with GSM options, timeline, and a line-item price within one business day.
QC & Logistics
Quality You Can Measure. Freight Without the Finger-Pointing.
Five inspection points before anything leaves the floor. QC team and logistics desk sit under the same roof — when a shipment arrives below standard or a freight bill comes in high, there's exactly one number to dial. One team, one call, one answer.
Five-Stage Quality Control
Incoming Material Inspection
- All fabric rolls and trim batches checked against production requirements before production
- Spectrophotometer shade verification under standard light box
- GSM tolerance verified to ±3%
- Failed materials rejected at the door
In-Line Production QC
- QC at cutting, sewing, decoration, and finishing stages
- Real-time defect flagging — issues corrected mid-batch
- Checkpoints at 50-unit intervals (small runs), 200-unit intervals (large)
Statistical Sampling (AQL 2.5)
- AQL 2.5 (Major) / 4.0 (Minor) per ANSI/ASQ Z1.4
- Stitch tension, seam strength, color — measured against golden sample
- Lot size determines sample size — each defect classified and photographed
Third-Party Lab Testing
- SGS, TUV, or Intertek testing concurrent with production
- ISO 5077 shrinkage, ISO 105 colorfastness, fabric composition
- GOTS/OEKO-TEX chain-of-custody documentation
- Lab reports in your name
Pre-Shipment Audit
- Random carton pull and full-piece inspection
- 100% needle detection verification
- Photo and video report for your approval before shipping

Sample Sign-Off
What Makes a T-Shirt Sample Pass.
Every check that decides whether a sample goes to bulk is measured, recorded and attached to the sample you receive — nothing is judged by eye.
| Check | How it's measured | Pass line | Evidence you receive |
|---|---|---|---|
| Fabric weight | Every roll weighed and checked against the requirement sheet before cutting starts. | ±3% of the tech-pack GSM target | Incoming material record |
| Colour match | Spectrophotometer reading against your Pantone TCX reference under a standard light box. | ΔE ≤ 1.5 | Lab dip and approved golden sample |
| Body measurements | Point-to-point measurement of every graded size against your chart. | ±0.5″ body, ±0.25″ neck and trim | POM report shipped with the sample |
| Lab testing | SGS, TÜV or Intertek, run alongside production rather than after it. | ISO 5077 shrinkage and ISO 105 colorfastness reported as conforming | Test report issued in your name |
| Bulk inspection | Statistical sampling of the finished lot to ANSI/ASQ Z1.4. | AQL 2.5 major / 4.0 minor | FRI report with each defect photographed |
Fit Check
Built for the Design That Isn’t a Stock Blank.
Where a cut-and-sew tee project fits this line, and which briefs are better served somewhere else.
| Boundary | What we take | Not a fit |
|---|---|---|
| Order quantity | 100 units per design per colour — adult and youth sizes count toward the same total | Under 100 units, or one colourway split across several styles to reach the number |
| Decoration | Up to five print locations — front, back, left or right chest, one sleeve | More than five decoration locations on a single tee |
| Colour approval | Pantone TCX dye matching and printed ink mixed on site | Final colour approved from a digital proof or phone photo — approval needs a physical swatch or chip |
| Size range | Adult and youth sizes in one order, with youth graded on its own block | Youth sizing squeezed into the adult grade to avoid a second block |
| Starting point | A sketch, reference tee, or tech pack — low-res art is redrawn as clean vector | A brief with no style, reference garment, or target fabric to build from |
If a project lands in the right-hand column, we say so on the first call instead of after a sample.
Ask About Your OrderWho This Is For
The Same Starting Point. Three Different Outcomes.
"I can't find a supplier who takes small orders seriously." That's where each of these founders began. What happened next had everything to do with who picked up the phone.
"Sent LeelineApparel a rough sketch of a heavyweight tee — 300 GSM, structured, 3D embroidery. They built the tech pack, sourced the ringspun cotton, and dialed the puff depth across three sample rounds in nine days. First collection sold out in three weeks.
Next order: 500 units. Same factory, same rep, same consistency. Over six collections, defect rate stayed under 1%. A sub-GSM fabric lot got flagged at incoming inspection — caught before cutting, not after."
Malik Carter
Creative Director, Heavy Goods Dept."As a children's brand founder, certification matters more than anything. GOTS and OEKO-TEX aren't nice-to-haves — they're table stakes for my customers. LeelineApparel gave me full chain-of-custody docs on each bolt, traced to the farm level.
Third-party lab reports before production. Water-based prints, compostable packaging. Four seasons, 14 SKUs, zero certification holds across 3,800 pieces shipped. Three independent spot tests commissioned by a UK retail buyer — all clean.
If the paperwork matters to your brand, this is the partner."
Elena Torres
Founder, Linden & Thread"No tech pack, no product sheet — just an idea and a lot of anxiety about minimums. The rep took a rough sketch, picked a 200 GSM fabric, and locked in a retail price that worked. First run: 100 units.
Sold out in 10 days. Second run: 300. Same fabric, same fit. Four reorders later, I am at 1,200 units a month — POM reports from run one and run five sit within 0.3″ on every checkpoint.
Every other supplier brushed off a 100-unit order as not worth their time. Three reorders later, it is still the same factory, same team, same consistency."
