Using A Partial Lengthwise Fold In The Pattern Cutting Process
A partial lengthwise fold is used When your pattern set includes cut on fold or double cut patterns and single cut patterns. In this instance, the fabric is folded at the needed distance parallel to the selvage. You should only fold the fabric at the needed distance based on the width of the cut on fold and or double cut patterns (if any).
A partial lengthwise fold is a great way to save fabric and and avoid stubborn creases from the fabric surface. It accommodates all basic types of patterns: single cut, double cut and cut on fold. This makes this fold extremely versatile and thus it is the most widely used when cutting sewing patterns.
As with anytime you fold fabric in the pattern cutting process, the folded edge should be perfectly parallel to the selvage edge such that the fold line is perfectly on the lengthwise grain. In addition, fabric face sides should be touching such that all marks that are transferred from pattern to fabric end up on the fabric's wrong side.
