Creases in paper can be a nuisance, but there are a few simple ways to remove them. One method is to use a warm iron. Place a damp cloth over the crease and iron it on a low setting. The heat and moisture will help to relax the paper fibers and remove the crease. Another method is to use a book. Place the paper under a heavy book and leave it for a few hours or overnight. The weight of the book will help to flatten the crease. You can also try using a hair dryer. Hold the hair dryer about 6 inches away from the crease and blow hot air on it for a few minutes. The heat will help to relax the paper fibers and remove the crease.
Removing creases from paper is important because it can help to improve the appearance of the paper and make it more presentable. Creased paper can be difficult to read or write on, and it can also be more easily damaged. Removing creases from paper can also help to extend the life of the paper.
