What tool is used to remove wrinkles or smooth fabrics during the sewing process?

An iron is the primary tool used to remove wrinkles or smooth out fabrics during the sewing process. It generates heat and steam that effectively relaxes the fibers in the fabric, allowing them to regain their flat and smooth appearance. This is essential for achieving a professional finish on sewing projects, as it helps eliminate any creases that may have formed during cutting or assembly.

While a pressing cloth can be used in conjunction with an iron to protect delicate fabrics from direct heat, it does not perform the function of removing wrinkles on its own. A steamer is also useful for removing wrinkles; however, it tends to be less precise than an iron, particularly for tasks like pressing seams. A fabric roller, while helpful in certain applications, is not designed specifically for smoothing or removing wrinkles from fabric, making the iron the most effective and common tool for this purpose in sewing.
