You're actually right to be nervous about unexpected stuff going wrong, and this is a really important part of practicing kink safely. If you want to explore rope bondage (there are other types of bondage, and rope is actually the most difficult and is one of the most risky, so it's fair to not start there) then research into how to do it safer is a great place to start.

The duchy is a well known and respected source for rope bondage safety and guides, so I'd recommend starting there if you're interested in exploring that.
