After some preliminary messing around, I found that I needed to go down a needle size to produce the proper gauge. This method of "stuffing" is easier than inserting thrums in the traditional way and makes nice little hearts all over the mitten.
Here's the inside, showing the fleecy lining.
The roving is so "sticky", for lack of a better word, that it's already felting together. It's hard to describe the thick cushiness of the fabric, but if you live in a part of the world where a single layer of knitted fabric doesn't cut it in January, you might want to give these a try.
P.S. What's with NBC? We've noticed that there's a dearth of live olympic coverage from the U.S. and what's shown in the evenings is heavily edited (not to mention filled with ads). Somehow, it seems disrespectful to the audience. So glad we have the option of watching CTV's live coverage--much more thrilling to see Bolt win the 100 metres as he actually does it!
