@carmeldog there are a few things you can do, you can cut 6 strings folded in half, use the 10 strings as usual, then for the 11th and the 12th strings, because you only need 11 you can treat both of them as one.
I recommend making a loop with this one, to keep things simple. You can check out Kinsey's tutorial named "how to: alpha triangle ends" there she shows how you can do it with triangles after loop, but the sane can be done with a normal loop as well
You can also check out Alex's tutorial "beginning loop with odd number of strings"
