I think I made a mistake once with the slipknot. It came undone when I put my weight on it. I had tied it wrong. The other few times, I think I made a mistake with the bowline (before I decided on the figure-8 knot) and then with the figure-8 knot. It took me a while to figure out how to tie the figure-8 knot the right way.
Do you have any idea which slipknot is the "right" one? This one?

Or this one, which I've used each time, and has never come loose (except for that time I made a mistake)
I've been using the latter each time and I hope I have the "right" one. I know the 2nd one tightens the more pressure you apply, but I want to make sure I'm using the strongest option? I just practiced with the figure-8 knot on my shower beam and I put all my weight on it to make sure it wouldn't come loose. It didn't, so I must've finally figured it out. It tightened so much I had to cut it off with a knife and throw the scarf away (I plan on using a rope when the actual day comes, not a scarf.) I've practiced with a slipknot over 50 times I think, put all my weight on it (sat on it, while holding onto the shower beam, which I wouldn't recommend because you could fall and hit your head) and it never came loose, so I must have the slipknot correct. I want to know that that's the best option though, and not the knot in the first picture. Those 50 times I practiced by putting all my weight on the noose, I hadn't really tied the ligature point knot in a particular way. I just looped it around a bunch of times to my own liking. It didn't come undone, so I'm unsure if I should just do that on the day I actually ctb, or that would be risky, and I should go with the figure-8.
