How to Sew Knits: 16 Tips for Sewing Knit Fabric

Knit fabric is made of yarns or threads looped around each other. When the fabric is pulled, the loops pull against each other. The space in between creates space for the fabric to move and stretch.

Knit fabric comes in all weights and stretches. It can be made from every single fiber or fiber blend. Clothing made from knit fabric can be tight and fitted, or it can be loose and draped.

Know Your Knit Fabrics

Here are a couple of examples of fabric: - Rayon spandex - Cotton spandex jersey - Sweatshirt fleece

To figure out the stretch percentage, line up the cut edge of your fabric next to a ruler. Hold the fabric at the selvedge and at 4″ and stretch the fabric as wide as it goes. Then release it and see if the fabric returns to 4″.

Use The Correct Sewing Machine Needle

Each needle comes in different sizes, which correspond with the weight of your fabric: smaller needles go with lighter-weight fabrics, and bigger needles go with heavier-weight fabrics.

The most accurate way of cutting out knit fabric is to use a cutting mat, pattern weights, and a rotary cutter. Rotary cutters make cutting curves and notches easier.
