Cowritten with Star Athena, this puzzle was an extra included in her monthly sock pattern subscription service. That month's theme was Agatha Christie, so we created a puzzle to appeal to those who know mysteries and knitting.
The homonym for 61D is 68A, not 67A. That said, I'm a mere knitter wanna-be (real soon now) so I had to look up several terms, including lace frogging. I learned what it was, but not the answer - until I worked the adjacent clues. It made me laugh. Relaxing subjects too. Fun!
