A method for preparing cross-sections of yarn samples along the plane perpendicular to the yarn's longitudinal axis is disclosed. This method involves the steps of passing the yarn through a hollow capsule so that the axes of the yarn and the capsule are aligned in parallel, tensioning the yarn to remove any crimp, forming a solid stub inside the capsule to fix the position of the tensioned yarn, and then cross-sectioning the stub perpendicular to its longitudinal axis.
