"Not sure which pattern you should use? Let's look in the book - oh, here! Now let's get you some yarn... and needles... ooh, and a bag to keep it all in!"
Lord knows I'm constantly making a mental list for myself:
"Oh, wouldn't this yarn make a fabulous [insert object] for [insert name]," or, "I could see a reason why I might need [insert pattern] on hand someday."
Hmmm. OK, so maybe it's not a bring-home-a-paycheck situation so much as a keep-a-scary-habit-self-supporting situation. I can live with that.
