Knitwear Pattern Making and Draping: How Fit Gets Built

Short answer: knitwear pattern making builds a pattern around fabric stretch and recovery, so a knit block uses less wearing ease than a woven block and grades differently. Patterns are made from a base size, tested on a fit model, then graded across the size range — and for knits, the pattern must also allow for shrinkage and for the relaxation that happens after washing.

Pattern making is the step where a design becomes a garment that actually fits. For knits, it is meaningfully different from wovens, and buyers who understand the difference ask better questions at sampling.

Why Knit Patterns Are Different

A woven block applied to a knit produces a garment that is too loose and loses shape.

The Steps in Pattern Making

1. Base block and measurements

Start from a base size and a points-of-measure (POM) table. The block encodes your intended fit: slim, regular or oversized.

2. Pattern drafting and adjustment

The pattern is drafted and adjusted for the specific style — neckline, armhole depth, hem, seaming.

3. Toile or fit sample

A physical sample is made and tried on a fit model. Measurements are checked against the POM table with tolerances.

4. Grading

Once the base size fits, the pattern is graded across the size range. Grading increments differ for knits and vary by silhouette.

5. Production pattern

The approved pattern becomes the production pattern, and marker making follows for cutting.

Knit-Specific Pattern Considerations

Draping vs. Flat Pattern Making

Knits are usually flat-patterned because their stretch is predictable, but draping helps with unusual silhouettes and asymmetric designs.

What Buyers Should Ask

Ownership matters: if you change factories, a pattern you do not own cannot travel with you.

Fit Testing: What to Check

A fit sample in the wrong fabric is not a fit sample. It must be the production fabric.

Common Pattern Problems in Knitwear

Conclusion

Knitwear pattern making builds fit around stretch, recovery and shrinkage, which is why knit blocks differ from woven ones. Work from a clear POM table, test on a real body in production fabric, grade deliberately and confirm shrinkage. Buyers who understand the pattern stage ask the questions that prevent the two most common knit fit failures: wearing ease copied from wovens, and shrinkage that was never in the pattern.
