indecision

Have to make a decision - I have officially finished the straght section (have dropped 12 stitches). I think I need to increase the length a bit, but I am not sure if I should do 14 or 15 dropped stitches. I want to avoid unlucky 13, and I am slightly swayed by the fact that 15 repeats would be divisible by 3, which will give it something in common with the 12 repeats that are called for in the pattern.

I am such a numbers geek.
