Go to www.tooltron. They have mini seam rippers that are amazing . Like miniature scalpels. I buy them by the dozens. The price says $1.50 but they gave always come through at $1.00. Maybe because I buy so much! I use them especially for taking out tiny stitching mistakes in paper piecing. I pick out the first couple of stitches with a conventional seam ripper then finish the job with the mini. Our guild bought a hundred of them for part of the member gifts for our Christmas party. When I teach paper piecing I always give one to each class member.
