I don't think there is a template. I have one fly on FOTW and suggested to webmaster I might send a couple more (haven't got around to it yet!). No template was suggested at that time. When I did mine I printed a couple of FOTW articles I respected and followed that sequence. I also imagined I was teaching a class so I made sure I took a pic at each point of discussion and wrote about the step. In fact I did project the sequence on a screen when I taught it at the club.
I shoud get on to those ones I promised!
