Very often fabric near the selvage is unused and discarded, as it may have a different weave pattern, or may lack pile or prints that are present on the rest of the fabric, requiring that the selvage fabric be cut off or hidden in a hem. Since industrial loomed fabric often has selvages that are thicker than the rest of the fabric, the selvage reacts differently. It may shrink or "pucker" during laundering and cause the rest of the object made with it to pucker also.
