Yes, I have advice. Watch Amy's video here of the demo of the North Country Cotton Baby Sock. It will show you the idea behind the heel flap, heel turn and picking up the guesset stitches and decreasing back to the original stitch count. It won't follow the pattern of Silver's tutorial, but it will show you the theory behind this section of the sock.
Go down a bit to "Working the heel of a sock".
Once you finish this one, you'll either be addicted to sock knitting or you'll never want to knit socks again. Me? I'm an addict. Good luck.
