Over the weekend I picked up a poncho liner and made myself a PLUQ using the "no sew version 2" method (separate gathering cords and suspension cords).

Decided to give it a try tonight in the basement with my ENO DN. I attached the shock cords to the suspension clips, cinched it tight, cinched the gathering cords tight, and climbed in... Only to discover that laying on a slant leads to suspension cords across my forehead! This took just a few minute to start giving me a headache...
What did I do wrong?

Here are some pics:

Here the cord is running across my head:
