I said I'd talk more about the process, and here's an attempt to do just that.
I made one of the potholders today. The pattern said to use one layer of Insul-brite, and one of warm and natural. I'm pretty sure that will keep your hands from burning, but geesh, that potholder was hard to hand sew shut---you know, the hole where you turn it right side out? I think when I make another one, I'll use less padding. Here's a picture of it. Hopefully next time, I'll get the mistakes corrected, and a neater result.
