lack the dexterity to tie flies (cf. handwriting, shoelaces etc.)

therefore frustrated.


Indeed, that would be my major worry in this case. I doubt that many
kids under 10 will be able to do it at all, and the aptitude across a
group of even ten year olds will vary massively.

I refuse to try and teach fly-dressing to kids under 12, and only then
when they comme along with their parents to a club evening and show
interest.

Fly-dressing is not a "casual" skill, and can also be very very
difficult indeed for kids generally.
