The Shirring Calculator takes the guesswork out of working with elastic thread and gathered fabrics.
Every fabric and elastic combination shrinks differently when shirred, so this tool does the maths for you.
Simply input the results from your swatch test (before and after shirring) along with your body measurements, and the calculator instantly generates your custom cutting dimensions.
Once you’ve entered your details, you’ll also receive a downloadable PDF plan that you can print or save, giving you a personalised cutting guide you can return to every time you sew.
