Yeah, the proper knot shouldn't flip up like a granny knot. Granny knot is what I did in the decades until I stumbled across Ian's website. Granny knot would always come undone.

You're making a granny knot. If you want the loops to stay sideways, you have to reverse directions between the first and second half of the knot. If you tie the first half left-over-right, then the second half has to be right-over-left.
