I am underway in building three 8’6″ 6wt fly rods for my son in laws as a 2024 Xmas gift, and want to include a fly box with flies with the rods. Like me, all three are beginners in fly fishing! My question for this group, if you had one fly box suggestion for a beginner, what flies (thinking several of each type so lets make this top 12 with four each), what would you put in that fly box? They live in OH, PA, and the third is Military and currently in CA. I am also putting together a leader wallet, so I can hopefully have rigs for dry, nymphs, and streamers! I want to build the rods, tubes, leaders, and flies for the fly boxes. Suggestions welcome on what I should plan on tying for them! Thanks!!
