Can someone please explain as simply as possible, how a knot in full suspension slips and any ways to minimize that risk? It took me quite some time to learn how to tie a slip knot, I think I'm doing it right but not very good at all with making/fixing things it's truly embarrassing how unskilled I am so I'm worried about how good a job I did, I put the loop around my arm and pull, it gets tighter. Any guidance would be really appreciated.
Edit: I plan to use 1/2inch double braided nylon dock line, 650lb working load limit, Everbilt brand
