My hairstylist left the state, I have severe trust issues so I've been trying to cut my hair myself. I have a V shape and long layers so I tried this haircut to just trim the ends. It came out alright, not as good as my hairstylist would have done but acceptable. I still recommend you go to a hairstylist but for anyone like me, this might help. I trimmed very little this first time, I'm planning to trim just a little bit over the next few washes as I get used to it, no more than maybe 2 inches total.
Oh, she lost me at 'consistent curl pattern'. Good luck though - curly hair is pretty forgiving, you don't need a precision haircut for it to look good. More about the overall shape and I think your strategy of a two week haircut is good, keep adjusting till it's how you want it .
