I am taking my family to the sow bug roundup in Mountain Home AR again this year. I've built each of my boys their own fly rods and they are feeling inspired by the upcoming sow bug, and their new rods, and want to tie some flies of their own.

What would be an easy emerger pattern for ages 6,8 & 10 to tie and hopefully catch a few trout on Dry Run creek. Han's olive and quill is what I am thinking. They will also be tying some zebra midges.
