My 12 year old son has started tying his own flies and is keen to learn/tye more. So far he has tyed woolybugger, AP nymph and a type of midge. Any suggestions for flies he should learn to improve his overall skills wold be grealty appreciated. I have him working on thread control but there is only so much of that he can take before school starts. I'm taking him fishing this fall in the Ozarks and hopefully the flies he ties he will catch trout on.
