Open cloth
Start lower and expect more drape and space between threads.
Weaving sett chart
Common EPI starting points for weaving yarns
Use this chart as a first estimate, then sample. The right sett depends on fiber, twist, structure, beat, finishing, and the cloth you want.
| Yarn | Plain weave | Twill / firm cloth | Notes |
|---|---|---|---|
| Bulky knitting yarn | 4-5 EPI | 5-6 EPI | Best for open scarves, blankets, and texture. |
| Worsted knitting yarn | 7-8 EPI | 9-10 EPI | Common rigid heddle starting range. |
| DK / sport | 10-12 EPI | 12-15 EPI | Useful for scarves, towels, and lightweight cloth. |
| 8/4 cotton | 12-15 EPI | 15-18 EPI | Good for towels and household cloth. |
| 8/2 cotton | 18-20 EPI | 22-24 EPI | Classic towel and yardage yarn. |
| 10/2 cotton | 22-24 EPI | 28-30 EPI | Finer cloth, napkins, and yardage. |
| 20/2 cotton | 30-36 EPI | 40+ EPI | Fine yarn; sample carefully. |
How to use the chart
Choose the row closest to your yarn, then pick the lower end for open cloth and the higher end for firmer cloth. If your yarn is unusual, use the WPI-based sett calculator.
Balanced cloth
Start near the middle and keep EPI/PPI close.
Firm cloth
Start higher, especially for twills, towels, and dense structures.
