What seam allowance is achieved by following the outside edge of the presser foot?

The correct answer of one-fourth of an inch is achieved by following the outside edge of a standard presser foot. Presser feet are designed for various seam allowances, and the one-fourth inch seam allowance is particularly common in quilting and other sewing projects where precision is key. By aligning the edge of the fabric with the outside edge of the presser foot, sewists can create consistent seams that conform to this measurement without needing to use a ruler or additional tools.

This technique emphasizes the importance of using the presser foot itself as a guide, which streamlines the sewing process, especially for beginners or in situations where maintaining a standard seam width is crucial for the overall fit and structure of the garment or project.
