How to tie shoelaces

How the heck do you teach a child to do it? DS1 is 5 1/2 yo. Tried this
morning, again. He couldn't/wouldn't even copy holding the laces 5cm from the
thumb knot (the knot you make to start), let alone *make* the thumb knot.
Fortunately his school shoes have velcro -- a deliberate choice by me!

At what age do kids typically learn to tie their shoelaces? And how do you
teach it?
