Yarn Yardage EstimatorSpinning Guild
Calculate projected finished yarn yardage from roving weight based on target grist and ply counts.
Volume Preservation Note:
Plying reduces total finished yardage to approximately 1/2 of the original singles thread length. An average 8% twist contraction has been incorporated to account for length lost due to spiral plying compression.
