What do you do when pattern says lay on selvedge?

When a pattern indicates to "lay on selvedge," it means that the edge of the fabric (the selvedge) should be aligned with the cutting line of the pattern piece. This is done to ensure that the grain of the fabric runs parallel to the selvedge, which helps maintain the fabric's stability and drape. Make sure to position the pattern piece appropriately, allowing for any notches or markings to align correctly. After laying it out, double-check that you have enough fabric to cut the entire piece while adhering to this guideline.
