Navy Parachute Rigger (PR) Introduction and Sewing Practice Test

The main idea is to transfer pattern outlines and important sewing guides onto the fabric so you can cut and assemble pieces with accuracy. Chalk or markers create visible seam lines, notches, and pattern markings that align panels correctly and establish proper seam allowances. These marks are temporary and removable, which keeps the fabric from being permanently altered or weakened while you prep and sew. In parachute rigging, precise markings ensure panels line up and the stitching follows the intended path, giving you consistent fit and strength. Coloring for style, cleaning the fabric, or protecting it during cutting aren’t the purposes of these markings.
