He's got a couple posts on it, in the workshop thread, "what are you working on". ( within the last two years )
But I can tell you how he taught me.
He said....just pin it, you sissy. U can always unpin it, if it isn't going right, and try again.
Practice, practice, practice.!
The more you do it, the better you'll get.
Pinning together popsicle sticks, is good practice
