A seam ripper is a small sewing tool designed to remove stitches from fabric. It typically features a pointed end for lifting stitches and a curved blade that cuts through thread. Seam rippers are essential for correcting mistakes in sewing projects, allowing crafters to easily undo seams without damaging the fabric. These tools come in various sizes and designs, often with a comfortable handle for better grip. Seam rippers are commonly used by seamstresses, tailors, and hobbyists alike, making them a staple in any sewing kit. Proper use of a seam ripper can save time and effort in the sewing process.
