I made Norma's Magic 28 Socks with a twist - I used US size 5 dpns and 1 100g skein of Paton's Classic Wool Merino and cast on 36 sts. I guess I should call them Magic 36 socks.
Just use 36 wherever the original pattern says 28 and do the math (half the sts (18 where the pattern says 14, etc). Adjust the heel flap accordingly. You can really make any Magic # Sock you want!
