OF:

You are not alone! It happens to me too! I found this happens to me on evenings when I am a little more tired. I find if I put tying aside for a few days, it gives me time to think about the sequence of tying the fly pattern. Then I give it another try, but not in the evening, in the morning like on the weekend when I am fresh and not rushed. It seems to help for me.

I hope this helps.
