In Biology we took a test the 1st half of class. After I was done, I took out my hat to work on until it was time for notes. When most had left during the break between, the teacher told me her mother crochets and is trying to knit, but her hats look funny and are pointed at the top. (I thought the way she said it was hilarious!) Then we started taking notes on DNA. During it, she said that DNA uses older strands to make new ones, and that just like she saw someone knitting a hat earlier with a pattern, the old ones were used as patterns.
See? You can interject knitting anywhere.
