Calculate total yarn yardage for weaving projects including warp and weft. Estimate cones needed from project dimensions and yarn weight.
Calculate warp yarn requirements for loom weaving projects. Estimate total warp threads, yardage, and sett from project width and EPI.
Calculate optimal weaving sett (EPI and PPI) from yarn wraps per inch and weave structure. Balanced, warp-faced, and weft-faced sett guide.
Multiply total batch weight by each fiber's target percentage. A 100g batch of 70/30 wool/silk needs 70g wool and 30g silk.
Component weight = Total weight × (Percentage ÷ 100)Weigh each fiber after blending to verify ratios. Adjust by adding more of deficient component.
Percentage = (Component weight ÷ Total weight) × 100Different fibers have different densities. A cup of silk weighs less than a cup of wool — weight ratios ensure consistent blend percentages.
Always blend by weight, not volumeUpdated: July 2026
500g total blend: 350g merino top + 150g silk sliver. Card together on drum carder for luxury sock yarn.
60% wool + 25% mohair + 15% nylon for 200g: 120g + 50g + 30g. Verify percentages before carding.
Have 80g wool and need 70/30 blend — total batch = 80 ÷ 0.7 = 114g, add 34g silk to complete ratio.
Creating consistent fiber blends requires accurate weight ratios. Enter target blend percentages and total batch weight to calculate grams or ounces of each fiber component, or determine blend percentages from component weights.
