When we began our road trip and I started these finger puppets, I could not, for the LIFE of me, figure out how to seal the edges - what's referred to as an "overcast stitch." After 30 minutes of failed attempts and frustration, I gave up.
Jack noticed (so, it's not hard to notice when I'm frustrated) and asked what was wrong. I showed him an example of "impossible stitch." He glanced at it and responded, "When we pull over I'll show you how to do it."
Sure enough, at the next stop he took the needle, thread & felt and, on the FIRST attempt, demonstrated a perfect overcast stitch.
I asked him where he learned it (and what else he'd been keeping from me), and he said, "This is the same stitch we used when we made apple potholders in Mrs. Moses' class. Don't you remember? You were there."
