Three weeks ago, I cut a big hunk out of my left index finger, it wouln't stop bleeding, so I went to emergency clinic, since there was nothing to stitch to, the dr. put silver nitrate on it then cauterized it. Wore a big honking bandage and finger guard for two weeks, still wearing a bandaid. It's very tender and draws at night. Oh, I was cutting white fabric, and, not a drop of blood got on it. that was my first rotary cutter accident and now I am uber careful. Happy Quilting!
