Help Regarding ligature for partial hanging.

[wunderwaffle]

I intend to ctb by partial. I have so far succeeded in blacking out with the method. I intend to secure my ligature to a doorknob and throw it over the door to hang on the other side. I intend to close the door for added support. Will my weight and the thrashing around cause the ligature I'm using- Paracord wrapped in soft fabric, to break. Specifically, by grinding against the edges of the closed door. Or by being squished between the door and the door frame. Rope experts? Help please!
