What additional step do napped fabrics need when folded crosswise?

When napped fabrics are folded crosswise, they require an additional step of brushing the nap in the same direction to prevent distortion and maintain the fabric's appearance. This helps to ensure that the fibers of the fabric lay uniformly and smoothly, preventing any potential inconsistencies in texture or appearance. Failure to brush the nap after folding crosswise may result in a visibly uneven surface or texture on the fabric.
