I KIP (or crochet) regularly, usually when I'm waiting for something or someone. People often watch and sometimes ask about it.
Over the weekend I was waiting for an appt, so pulled out an earflap hat (still need to weave ends & add a chinstrap) and started to crochet along the edge. Someone else came in and asked if it was knit or crochet, saying that she just learned how to knit a cable.
I showed her the hat (which has cables), explaining that it was knit but I was adding a row of crochet around the edge just to finish it off a bit. She said she had heard that crochet was easy but the bit she'd looked into seemed confusing. So I showed her a basic chain and how to make some crochet sts. She thanked me for showing it to her and said she might try it now too, since seeing it one-on-one.
Cross-posted in the knit forum too. I give mini knitting lessons if asked.
