- [How many granny squares do you need?](https://threadcabin.com/explore/59/how-many-granny-squares-do-you-need.md): Turn a blocked, joined square measurement into rows, columns, and a separate spare count.

- [How much replacement yarn do two labels imply?](https://threadcabin.com/explore/61/how-much-replacement-yarn-do-two-labels-imply.md): Convert an original ball count into required length, then round replacement balls once.

- [How many whole balls does a length requirement need?](https://threadcabin.com/explore/62/how-many-whole-balls-does-a-length-requirement-need.md): An 850 m requirement with 10% reserve needs 935 m. At 200 m per ball, round 4.675 up to five balls: 1,000 m in total.

- [Estimate a rectangular project from a weighed sample](https://threadcabin.com/explore/63/estimate-a-rectangular-project-from-a-weighed-sample.md): A finished 10 × 10 cm sample weighing 5 g scales to 150 g for a 50 × 60 cm rectangle. With 10% reserve, plan 165 g before rounding packages.

- [How much yarn is needed when one yarn is held double?](https://threadcabin.com/explore/64/how-much-yarn-is-needed-when-one-yarn-is-held-double.md): For 400 m of working length held double, both strands travel the full distance. With 10% reserve, the requirement is 880 m of the single yarn.

- [Budget two different yarns held together](https://threadcabin.com/explore/65/budget-two-different-yarns-held-together.md): For 400 m of working length with one strand of each yarn and 10% reserve, yarn A and yarn B each need 440 m. Their lengths cannot be pooled.

- [Combine component quantities without mixing colors](https://threadcabin.com/explore/66/combine-component-quantities-without-mixing-colors.md): Two parts using 120 m and 80 m of color A total 200 m before reserve. Color B uses 60 m separately. At 100 m per ball and 10% reserve, buy three A balls and one B ball.

- [Estimate making time from a timed sample](https://threadcabin.com/explore/67/estimate-making-time-from-a-timed-sample.md): If 50 comparable units take 20 minutes, 500 units take 200 minutes at that sampled pace. A 15% time allowance gives 230 minutes, or about 3 hours 50 minutes.

- [Measure a motif after blocking and joining](https://threadcabin.com/explore/71/measure-a-motif-after-blocking-and-joining.md): Use the distance between corresponding points of joined motifs. An 11.5 cm loose square with a join adding 0.5 cm per repeat has a 12 cm pitch in this example.

- [Choose a layout when the target is not an exact multiple](https://threadcabin.com/explore/72/choose-a-layout-when-the-target-is-not-an-exact-multiple.md): A 125 × 180 cm target with 12 cm square repeats needs 11 × 15 motifs to cover it: 132 × 180 cm. Keeping only complete repeats inside the target gives 120 × 180 cm.

- [Replace a discontinued yarn when its original quantity is known](https://threadcabin.com/explore/77/replace-a-discontinued-yarn-when-its-original-quantity-is-known.md): Start with three original 200 m balls: 600 m. A replacement labeled 150 m/50 g needs five balls with a chosen 10% reserve. Confirm fabric suitability before committing to the quantity.

- [Plan a project with two yarns held together throughout](https://threadcabin.com/explore/78/plan-a-project-with-two-yarns-held-together-throughout.md): Keep one complete length budget for each yarn. For 400 m of working length plus 10% reserve, both A and B need 440 m, then their package quantities round separately.

- [Project finished dimensions from a before-and-after sample](https://threadcabin.com/explore/79/project-finished-dimensions-from-a-before-and-after-sample.md): A sample changing from 10 × 10 cm to 11 × 9 cm grows 10% in width and shrinks 10% in height. A comparable 50 × 60 cm piece projects to 55 × 54 cm.

- [Plan a multicolor project from separate color samples](https://threadcabin.com/explore/80/plan-a-multicolor-project-from-separate-color-samples.md): A useful color budget records each color’s own consumption. In this example, two A components need 120 m and 80 m, while B needs 60 m. With 10% reserve and 100 m balls, the result is three A and one B.

- [Plan a granny-square blanket from sample to assembly](https://threadcabin.com/explore/83/plan-a-granny-square-blanket-from-sample-to-assembly.md): A 12 cm joined square repeat gives 150 squares in a 120 × 180 cm field. With 5% spares, make 158. A timed sample of two complete squares in 30 minutes gives 39.5 hours before time allowance.

- [Budget each color in a multicolor granny project](https://threadcabin.com/explore/84/budget-each-color-in-a-multicolor-granny-project.md): For twenty motifs, a measured 6 m of A and 4 m of B per motif gives 120 m A and 80 m B before reserve. A separately measured 30 m A joining requirement raises A to 150 m.

- [Make a representative finished swatch](https://threadcabin.com/explore/107/make-a-representative-finished-swatch.md): Use the project’s stitch pattern, working direction and finishing treatment. A smooth flat sample does not represent a textured circular garment.

- [Measure stitch density away from edges](https://threadcabin.com/explore/108/measure-stitch-density-away-from-edges.md): Count complete stitch intervals across a central measured width. Do not include a tight selvedge or stretch the ruler span to obtain a desired result.

- [Measure row density consistently](https://threadcabin.com/explore/109/measure-row-density-consistently.md): Count rows along the working axis and state whether ridges represent one or two rows. Measure a finished central area, not an unstable starting edge.

- [Measure blocking changes on both axes](https://threadcabin.com/explore/110/measure-blocking-changes-on-both-axes.md): Record width and height independently before and after finishing. A sample can grow wider while becoming shorter.

- [Record sample measurements and behavior](https://threadcabin.com/explore/111/record-sample-measurements-and-behavior.md): Record numbers alongside the exact material, tool, stitch pattern and finishing method. Add observable behavior rather than only a gauge total.

- [Include assembly and finishing time](https://threadcabin.com/explore/118/include-assembly-and-finishing-time.md): Separate active making, active finishing and passive drying time. A percentage buffer cannot represent an overnight drying dependency by itself.

- [Measure remaining material from a label](https://threadcabin.com/explore/121/measure-remaining-material-from-a-label.md): For one uniform yarn, estimate length from net remaining mass and the original length-to-mass ratio. Remove packaging and keep uncertainty from scale resolution visible.

- [Work with mixed length units](https://threadcabin.com/explore/123/work-with-mixed-length-units.md): Convert each length into one working unit before adding or comparing it. Keep the source value and round only the final displayed result.
