After trying more seam rippers than I can remember, I finally found the Clover white round handled one is wonderful. Now, if I could just find more of them...cause you know I've got to have one in each room w/each machine and then back-ups too. Right now I've got a table runner I need to take apart. Not cause my friend isn't happy, she is. It's me, I didn't make the oval ends rounded enough and every time I looked at it, it bugged me big time. So now it's on the redo pile. I don't mind redoing. If I could find the fabric, which I got at a yard sale years ago, I'd just make her another. But no, I've used it all up. It's it the case the odd pc of fabric you find is what is loved the most.
Anyway, about the seam ripper, check out Clover's, you might like it.
