Weaving Draft

Project width (finished)

Project length (finished)

EPI / Sett (ends per inch) PPI (picks per inch, weft density) Loom waste inches — rigid heddle typical 18–24" Take-up % draw-in + take-up — typical 10% Shrinkage % (wet finishing) typical 5–15% depending on fiber Heddle/reed size

Warp yarn name Warp weight Yards per skein Weft yarn name Weft weight Yards per skein (weft)

WPI → EPI helper

Wraps per inch

For plain weave on rigid heddle: EPI ≈ WPI ÷ 2. Suggested EPI: —

For weft: PPI ≈ WPI ÷ 2 to ÷ 3. Suggested PPI: —

Warp ends

—

finished width × EPI, +2 floating selvedges

Warp length per end

—

length + take-up + shrinkage + loom waste

Total warp yardage

—

ends × warp length

Weft yardage

—

picks × width-in-reed (+ 10% buffer)

Warp skeins needed

—

Weft skeins needed

—

Width in reed

—

finished width × (1 + take-up%) × (1 + shrinkage%)

Total picks (weft rows)

—

length-on-loom × PPI
