Frequently Asked Questions

Does all cotton shrink?

Most untreated natural cotton shrinks when washed for the first time. 'Pre-shrunk' cotton shrinks less, but a test wash is always recommended.

How do I prevent cotton shrinkage?

You cannot fully prevent natural shrinkage, but washing in cold water and air drying can minimize it. It's best to pre-wash fabric before sewing.

Linen fibers relax significantly when washed. Expect 5-10% shrinkage loss. Plan your yardage accordingly to avoid shortage.

Rayon / Viscose Shrinkage Tool

Rayon is notorious for shrinking. Calculate the high loss rate (often 10%+) before cutting your pattern.

Wool Shrinkage & Felting Calculator

Wool can felt and shrink dramatically if agitated. Use this to calculate loss for felting projects or pre-treatment.

Denim / Jeans Shrinkage Calculator

Raw denim and heavy cotton twills often shrink significantly in length. Expect 10-12% shrinkage for unsanforized denim.

Silk Fabric Shrinkage Calculator

Silk, especially Crepe de Chine, can shrink 5-8% when washed. Dry cleaning minimizes this, but hand washing changes the texture.

Cotton Flannel Shrinkage Calculator

Flannel is loosely woven and brushed, leading to high shrinkage rates (often 8-10% or more). Buy extra yardage.

Polyester / Synthetic Shrinkage Tool

Polyester is very stable. Shrinkage is usually minimal (under 2%), but high heat drying can cause permanent creases or damage.
