The ease refers to the room that
is given to allow the fabric to drape and make wearing a knitted garment
comfortable. The ease tends to affect the width rather than the length and is
typically calculated from the bust or hip measurements. Ease is either added or subtracted from the
actual body measurements to accommodate how the garment fits and drapes. Understanding
the ease will allow you to knit garments that fit your body and personal style
preference.

Positive Ease
This will add to the finished
measurements making the garment bigger than the actual body measurements. A
positive ease allows for movement and has a roomy effect allowing the garment to
drape. Sweaters and jackets will typically have a positive ease.
Negative Ease
This will subtract from the
finished measurements. A negative ease will be form fitting and will hug the
body rather than draping. Knitted hats
would be a good example of an item that would require negative ease so that it
stretches to allow it to cling to the wearer’s head.

The weight of the fabric will also affect the ease. A heavy fabric or a
hairy fabric such as mohair will require additional ease of at least 2” while a
light-weight fabric may not require any additional ease. The fiber contents can also affect the way
the fabric drapes. A yarn with a stiff fiber content will require additional
ease to allow for movement while a ribbon yarn may not require any ease at all.
A designer will take into
consideration the intended use of the garment, design style, the weight of the
yarn as well as the fiber contents when designing a garment.
