So, I was a nurse for 30+ years. In that time ran a catering company and later, a restaurant for a blessedly short time. I CANNOT GO PAST A MISTAKE! If I just knit on it's like admitting defeat. The first thing I learned to do when learning to knit was to tink. My instructor said,"It's an important part of the process."
I'm glad that there are sites on the net that show newbies how to tink, and to let them know that it's nothing to be ashamed of.
