fold line

Definition

The fold line is the folded edge of a fabric that has been laid double. It is not cut along this edge so that, when the fabric is opened out, a symmetrical pattern piece results.

Use in the textile industry

The fold line is used in mass production and in cutting operations when symmetrical pattern pieces — such as fronts, backs, or sleeves — are to be cut in a single cutting step. The fabric is folded lengthwise or crosswise relative to the selvage so that the fold line serves as a temporary axis and both layers lie exactly on top of each other. This method saves time and ensures that mirrored pieces are identical in shape.

Frequently asked question

The selvage is the finished lengthwise edge of a woven fabric that is formed during weaving and defines the lateral boundary of the fabric width. The fold line, by contrast, is created only by folding the fabric during cutting. It is not an original fabric edge but an artificially produced fold that is no longer visible once the pattern piece is opened out.
