Frequently asked questions

What is Quilt Binding Calculator?

Binding length, number of strips and fabric needed to bind a quilt of a given size.

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 Quilt Binding Calculator different from Beading Pattern Calculator?

They sit next to each other but answer different questions. Beading Pattern Calculator: total beads and finished size for a loom or peyote pattern from rows, columns and bead size. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Candle Wax Calculator is the closest one after this: Turn a container's volume into the wax weight and fragrance oil you actually need, for soy, paraffin, coconut, beeswax, palm or a blend — in oz, grams and pounds.

What else is worth having open alongside it?

Crochet Hook Size Converter and Cross-Stitch Floss Calculator — 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-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.ExplainerThe Aida Count Sets the Size, Not the ChartThe same 100 × 120 chart finishes 23 cm wide on 11-count and 11.5 cm wide on 22-count — twice the width, four times the area, from one number on the fabric label.ExplainerThe Flat Pattern of a Cone Is a Sector, Not a CircleRoll a 50 mm cone 80 mm tall and its pattern is a 190.8° slice of a 94 mm circle. Flatten a nearly cylindrical lampshade and the pattern radius runs to 839 mm — the shallower the taper, the further away the apex.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-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.
