Frequently asked questions

What does Cross-Stitch Floss Calculator do?

Estimate how many skeins of floss a design needs from stitch count, strands and fabric count.

When would I actually use this?

Buying the right amount before starting: how many skeins a jumper needs, how much wax fills the moulds you own, how much resin a bezel takes, how much fabric a quilt binding eats.

What is the most common mistake?

Sizing from the pattern's yarn rather than your own. Two yarns sold as the same weight can differ by a fifth in metres per hundred grams, and a hook or needle size converted between systems is a nominal diameter, not a promise about gauge — knit a swatch.

How is Cross-Stitch Floss Calculator different from Cross-Stitch Size Calculator?

They sit next to each other but answer different questions. Cross-Stitch Size Calculator: finished design size from stitch count and fabric count, in inches and cm, with an optional margin. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Beading Pattern Calculator is the closest one after this: Total beads and finished size for a loom or peyote pattern from rows, columns and bead size.

What else is worth having open alongside it?

Candle Wax Calculator and Crochet Hook Size Converter — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Hook and needle equivalences follow the Craft Yarn Council's metric table; the soap calculator uses published saponification values, which vary by oil batch, so the lye figure is a starting point that a superfat margin is meant to absorb.

How-toEstimating Embroidery Thread From a Stitch CountThirty thousand stitches at 3.5 mm with fifteen per cent waste is 120.7 metres. The stitch count comes from the file; the average length is an assumption, and doubling it doubles the answer.ExplainerA Jar Is Sold by Volume and Wax Is Bought by WeightThe trade rule of 0.8 oz of wax per fluid ounce of jar is an effective density of 0.767 g/mL — calibrated for soy at an 85 per cent fill. It is right to within 0.2 per cent for soy and under-reads beeswax by six.ExplainerClay Shrinkage: Divide, Do Not Add a PercentageTo fire at 25 cm with 12 per cent shrinkage you throw at 28.41 cm, not 28. Adding the percentage instead of dividing by its complement leaves you 3.6 mm short — every time, in the same direction.ExplainerEvery Oil Blend Has Its Own Lye RequirementA thousand grams of olive oil needs 127 g of lye; the same thousand grams of a palm-coconut-olive blend needs 143. Saponification is stoichiometry, not a rule of thumb, and a five per cent error in one direction makes a caustic bar.How-toBinding a Quilt: Strips, Bias and the Fabric to BuyA 150 × 200 cm quilt has a 725 cm perimeter once you allow for the join, which is seven strips off a 110 cm bolt and six off a 140 cm one. The strip width you choose sets the fabric, and the corners set whether it lies flat.ExplainerFabric Yardage Is a Staircase, Not a SlopeTwelve pieces of 46 cm take 1.84 m on a 140 cm bolt. Make them 47 cm and it jumps to 2.82 m — fifty-three per cent more fabric for one centimetre, because the third piece no longer fits across.
