Often stretch sewing patterns will specify using a fabric with a certain amount of stretch factor. You will find that knits with different stretch factors will sew up differently and give a different look to your final product.

See how far it stretches. You should not stretch the fabric to its absolute limit. Just enough that it has strong tension but is not overstretched.

Stretch Factor of Fabric Formula

If you love math, this is how you work out the percentage of stretch:

(amount fabric stretched /starting measurement ) x 100

So if your 4 inches stretches to 7 inches, it stretched by 3 inches. Our formula is ¾ x 100 = 75% stretch factor.

How to Use the Stretch Factor of Fabric

For most stretch items like dresses and tops, it is the crosswise measurement that is important as this is the amount of stretch going around your body.

For items such as leotard sewing patterns and swimwear, you will also need to measure the lengthwise grain stretch. Some lycra swim and dance fabrics have a lengthwise stretch that is greater than the crosswise stretch and this can affect how you place your pattern pieces when cutting.

A good knit fabric should recover to its starting point after being stretched. This is called recovery. If your fabric doesn’t recover to its original position, you will find that after a short wear, your garment will look baggy and start to stretch out of shape.
