Here's the latest on my Firestarter sock:
As you can see I finished the gusset and heel on Sock #1. The construction is very interesting. First you knit in the round and increase to make the gusset, then you knit some short-rows to turn the heel, and then you knit back and forth until all the gusset stitches have been decreased. That's where I am now, ready to start knitting in the round again.
I've never knit a sock this way before, and it was lots of fun!
