Do: Be a confident crocheter.
Don't: Be a cocky crocheter.
Luckily, I made a wise choice to unravel it before bedtime so the next morning I could just pick up and go on. Since this incident a week ago (where does the time go?) I have gotten my meow back and am back to where I was before the unraveling. I am proud to say my width has remained consistent and I am back in the zone of a confident crocheter.... but I am constantly double-checking and counting those stitches and being very cautious not to tread again in the cocky territory.
