I had never considered what the little red ball on the seam ripper is for before I read a tip from Sew-licious. Since then I have saved a lot of time! Since using the seam ripper as it is designed for instead of picking out stitches and pulling them out gradually along the seam I have have had about 95% success. (On very thin fabric I have sliced a hole a couple of times.) If you have never considered where to place the red tip of a seam ripper please follow this link to Marti at Sew-licious
