Watching is unlikely to help. I tell scouts to practice them before bed and then practice them in bed after the lights are out.
Tieing them in the dark gives you practice on how the rope feels, the relationship of your hands, and how a well tied one feels.
A few of these kids have had to tie knots while assembling a tent in driving rain, lashing to a tree, tying them over their heads, etc (most of course have not!). Or tied something to car before highway driving. This is how they have the skill and confidence to do it right.
You only need a handful of knots and hitches as your go-to knots that will help you in 99.9% of situations you will encounter. You might as well learn them: they are some of humanity’s oldest inventions.
Plus the math can be fun.
