Is this a real sample?

No. A drawing so you can see how structure moves with the spec. Confirm on a sample.

How is sett calculated?

Ends/cm ≈ GSM × 45 / denier, assuming a square sett. Real programs can differ warp vs weft.

Inspect

Move the glass over a drawn cloth. Density, denier, ply, and finish change what you see. Not a mill photo.

110 GSM (3.24 oz/yd²) · 75 D / 36F · 1-ply · 280 cm

Move the pointer or use arrow keys. The glass shows filaments and ply. Sett is a square-sett estimate.

Home-textile starting points. Not pass/fail limits.
