Toe-Up Sock Cast Ons

We are looking at two separate ways to cast on yarn for a toe-up sock and one for the cuff-down socks. 
   The two cast on's for toe-up are very easy and make a very nice toe. When I start a pair of socks (toe-up,) I will use the spider version. I have also created a pattern for a very nice round toe that will be published here, also. It requires only 4 stitches per needle to start and forms a rounder toe than most toe-up patterns. 
   Let's start with the Wrap Cast on for Socks:
