Final answer:
To remove serged stitches, a seam ripper is the most suitable tool. It allows for precise cutting of stitches without harming the fabric, whereas tweezers can be used to pull out loose ends, and scissors risk cutting the fabric.
Step-by-step explanation:
To remove serged stitches effectively, the best tool to use is a seam ripper. This tool is specifically designed to cut and remove stitches without damaging the fabric. First, you should gently slide the pointed end of the seam ripper under the serged stitch. Then, push it forward to cut through the stitch. Once a few stitches have been cut, you can pull them out with either your fingers or with tweezers. If necessary, cut additional stitches. Using scissors can be risky as they might cut the fabric especially if the stitches are very tight. On the other hand, using pins may be less effective compared to a seam ripper or tweezers and can also damage the fabric if not used carefully.
