If you want to be able to trim off the ends, I suggest a double fisherman’s instead (aka the double overhand stopper) with both strands (hold them together while you tie and treat them as a single strand).

With either knot, after you trim, you can melt the ends of the elastic cord. It will “mushroom” a bit, which will also prevent the tips from creeping into the knot and coming loose.
I like to recommend the episode(s) on John McAfee when people first start Bastards. They’re wild and not nearly as dark/heavy as some episodes can be.
