I love the toe up “Judy’s Magic Cast on” and Liat Gat has an entire video playlist with step by step instructions for toe up socks on youtube. http://www.youtube.com/watch?v=dBcbKoaFjCc&list=PLE0A132B58E65D13F
Also there is a rounded toe increase on Ravelry published by Tanja Murray that gives a nice round toe as opposed to the longer pointier toe that is in traditional toe up patterns. http://www.ravelry.com/patterns/library/rounded-toe
