My kids love Miyazaki films:
My Neighbour Totoro
and most recently, Howl's Moving Castle.
Apparently there is a scene of knitting mice in Howl's Moving Castle. It could be some other Miyazaki-type creature, but one way or another, Oscar watched it and then wanted to learn how to knit. Enter Nana:
He got about three stitches done when his interest was captured by something else, being the 5 year old boy he is. But he keeps those needles in the kitchen and periodically asks me to show him how to knit again. We'll see if it sticks.
