Which tool is recommended for pressing curved areas of sewing projects?

The recommended tool for pressing curved areas of sewing projects is a tailor's hem. This tool is designed specifically to help press and shape hems and curved edges effectively. Its design allows it to fit into the contours of the fabric, helping to achieve a smooth finish without distorting the shape of the fabric. When working with curves, a tailor's hem ensures that the fabric is pressed accurately along the curve, which is essential for creating a polished and professional-looking result in garments or other sewing projects.

In contrast, the other tools listed are not specifically suited for this task. A seam ripper is used primarily to unpick stitches; a presser foot helps guide the fabric when sewing; and a measuring tape is used for taking measurements rather than pressing. Thus, the tailor's hem stands out as the most effective choice for addressing the unique requirements of pressing curved areas.
