Jonathan Farmer built Midnight Sun Custom Flies out of necessity — he started tying because he couldn't afford to keep replacing store-bought dries that lasted six or eight fish. That constraint turned into a business tying commercially for OPST and now running his own crew out of Alaska's Kenai Peninsula. What makes his flies worth studying isn't the fish-catching colors, it's the durability engineering underneath them. Here's how he actually builds a fly that survives cold water, sharp teeth, and a season of hard fishing.
Start With the Platform, Then Choose Materials
Farmer's design process runs backwards from how most beginners assume it works. He doesn't start with a material he likes and build a fly around it — he starts with a platform, or the overall shape and function he's after, then picks materials to fit that platform. He's candid that the first half dozen versions of any new pattern are usually garbage. Designing a fly, in his words, is a puzzle: you're solving for how the materials move in the water, how the proportions balance, and whether the thing actually survives a full day of fishing before you ever worry about what color it should be.
The Durability Tricks Most Tiers Skip
The details that separate a fly that lasts one fish from one that lasts a season come down to a handful of habits Farmer repeats on every pattern: doubling back the tip of a feather when tying it in instead of leaving a single fragile wrap, running a bead of crazy glue underneath a tinsel body so it can't unravel, and reinforcing dubbing loops so nothing comes loose after the first few takes. He calls it "preaching redundancy" — building in a second point of failure protection everywhere a fly typically comes apart, rather than hoping one wrap holds.
Material Choices That Actually Matter in Cold Water
One material call worth remembering if you fish cold winter water: Farmer leans on thin raccoon fur for winter patterns in the Pacific Northwest and Alaska specifically because it holds up in near-freezing conditions better than marabou, which he's seen crack and break when a hook is literally icing up between casts. It's a small substitution, but it's the kind of detail that only shows up after years of guiding and tying through real winter conditions rather than reading a materials list.
What "Graboid" and "Beast of Burden" Are Actually Built For
Farmer's signature patterns — the Graboid and Mini Me Graboid, the Led Zeppelin, and the Beast of Burden — aren't just named for fun (though he'll admit naming a fly is harder than tying one). The Led Zeppelin gets its blimpy, prawn-like shape and brass weighting from the same profile logic as a Zonker-style pattern, built heavy enough to get down fast for steelhead. The Beast of Burden is built specifically for the punishment of swinging flies through gnarly steelhead water session after session, which is exactly why the redundancy in construction matters more on these patterns than on a dry fly you might lose to a tree on the first cast anyway.
Gear for Tying and Fishing Durable Streamers
If you're building out a streamer box with the same durability mindset Farmer uses, the Mag Box Pro keeps heavier, bulkier streamer patterns organized and undamaged between trips with its magnetic fly docks. On the terminal end, a fly this well-built deserves a leader that can actually turn it over — the Platinum HOGzilla Furled Leader is a short, powerful sinking leader built specifically for streamer fishing. And for more on the philosophy behind building gear and flies that hold up, the Tips and Tricks for Fly Fishing eBook is worth adding to your library.
