I was taught the bowline and many other knots at church camp back in the 70's. I was taught you thro a loop in the line, then a rabbit (tag end of the line) comes out of the loop, goes around the tree ( the long end of the line and back into the hole, then pull tight. This is easy for children to remember so it has stuck with me these last 40 years. we used bowlines while I was working ship traffic and barge control. a bowline can be tightened with 300,000 tons of force and can still be untied, no other know can match this. this is easy for children to remember so it has stuck with me these last 40 years. the loop can be thrown right or wrong, thrown wrong there will be no bowline.

botht the bowline and hitch are easier to tie "freehand" or in the air. the hitch you make a loop in the rope, then a second loop, and criss-cross the loops... kinda hard to explain without being right there showing you. If you have to make a hitch around an object, then you wrap the rope around once, cross the top underneath the bottom right in front of you, wrap it around again, and put the trailing end under the "X" made in the first step. As for the bowline, the best answer I have for you is already posted by cgull.
