I'm so sorry about your finger. I too am proof that you can quilt with only 9 fingers. In 2006 I had a work accident and a saw blade took my right index finger. I have about an inch still there. I am even a receptionist that sits and types on a computer all day. I have gotten pretty fast at that too. So it is possible. I am so glad to hear that your finger is still there though. Here's to more quilting and be careful of the sergers they can be dangerous. :)
Blassings!
