The phrase describes methods employed to remove creases, folds, or wrinkles from a floor covering, restoring it to its original flat condition. An instance of this would be addressing a newly purchased rug that has been rolled tightly for shipping, or correcting buckling in a rug that has been in use for an extended period.
Maintaining a flat, even surface on a floor covering enhances aesthetic appeal within a space and mitigates potential trip hazards. Historically, techniques for achieving this have evolved from simple stretching and weighting to include more advanced methods utilizing moisture and heat. This ensures the longevity and continued usability of the item.
