Madison Rainbow Trout Trucker Hat

by @dekasso

Two rainbows turning in cold water

Two rainbow trout in a mountain river under snowy peaks, in olive green, rose pink and slate blue, for days spent on moving water.

Two rainbow trout cross a mountain river, one arching up while the other swims level below. Olive green backs, a rose pink stripe and charcoal spots sit over river teal water, sage banks and slate blue peaks.

  • Two rainbow trout in one river
  • Rose pink stripe, olive back, charcoal spots
  • Snow-capped slate blue mountain range
  • Sage green banks and teal riffles
  • Ten colour layers, sky to highlights

The cap

One design, four caps. The front panel is what the paint or the dye sits on, so it changes the hat.

  • A blank Trucker cap

Two finishes

The same design, made two ways. Pick one in the panel; the cap and the quantity are yours to choose too.

  • An airbrush misting pigment through a stencil onto a cap panel

    Hand airbrushed

    $85 for one hat, on a trucker

    Painted to order — would ship in about 2 weeks

    How it is made
    How it is made
    Sprayed by hand through this design's own stencils, one layer at a time, each left to dry before the next mask goes down.
    How it looks
    Soft gradients and hand-cut stencil edges. Every cap is a little different.
    What it sits on
    On a natural cotton twill front.
    Durability and care
    Water-based paint, heat set and sealed. It takes rain and a season on a boat; spot clean with cool water, never a washing machine.
  • A sublimation-printed cap panel peeled from the transfer sheet

    Sublimation printed

    $32 for one hat, on a trucker

    Printed to order — would ship in 5–7 business days

    How it is made
    How it is made
    The design is printed in dye onto transfer paper, then pressed with heat so the dye soaks into the polyester fibres.
    How it looks
    Full colour edge to edge, and identical every time.
    What it sits on
    On a white polyester foam front — sublimation only takes on white polyester.
    Durability and care
    The dye is in the fibre, not on it, so it will not crack or peel. Gentle wash, air dry.

The artwork

Two rainbow trout share one stretch of river. The upper fish bends into a curve, tail low, while the lower one holds steady with its mouth open. Behind them, slate blue mountains wear snow, and sage green brush lines both banks.

It wears well on a drift boat or a gravel bar, and just as easily at the fly shop counter. From across a room, people catch the rose pink band first, then the spots, then the peaks.

Rose pink over olive green is the layer to get right. Lay it as a soft band down the middle of each flank so the green still shows above and the cream below, and the fish read as alive rather than painted on.

Looking after it

Hand airbrushed

  • Spot clean with cool water and a soft brush. Never a washing machine.
  • Keep it out of a hot car for long stretches — heat-set paint is tough, but a dashboard in July is not a test worth running.
  • Reshape the brim by hand while damp.

Sublimation printed

  • Spot clean, or gently hand wash in cool water. No bleach.
  • Air dry. Do not iron the print.
  • Reshape the brim by hand while damp.
  • The dye is in the fibre, so the print will not crack or peel.

The layers

10 layers, in this order. Each mask comes off and the paint has to dry before the next one goes down.

  1. Sky
  2. Mountains
  3. Snowcaps
  4. Banks
  5. River
  6. Trout backs
  7. Bellies and fins
  8. Red band
  9. Spots and detail
  10. Highlights

The kit's stencil set is cut from these layers; with the cutter (12 hats and up) you cut your own from this design's layer files.

How to mix each colour

  • Pale sky blue

    1 part blue to 4 parts white, a drop of green so it does not drift purple

  • Slate blue

    White with blue and a touch of black, about 4 : 1 : ½

  • Snow white

    Opaque white from the bottle; two thin coats cover better than one thick one

  • Sage green

    2 parts green, 1 part white, a drop of black to dull it

  • River teal

    2 parts blue, 1 part green, a touch of white to lift it

  • Olive green

    2 parts yellow, 1 part black, a drop of red to warm it

  • Golden cream

    White with a drop of yellow and the smallest touch of brown

  • Rose pink

    1 part red to 4 parts white, a drop of blue if it looks salmon

  • Charcoal

    1 part white to 3 parts black, a drop of blue

Setup

  • Ventilation or a spray booth. Water-based paint still throws a fine mist, and you will be breathing it for hours.
  • A half-mask respirator rated for paint mists. A dust mask is not one.
  • A compressor with a moisture trap, set and tested on a card before you start: wet air spits water into the paint.
  • Reducer and a cleaning pot within reach, so a clog is a ten-second fix instead of a ruined panel.
  • Spray a test card for every colour before it touches the cap. Colour reads differently wet, dry and on twill.

Prep

  • Lint-roll the front panel. Every fibre left on it prints as a speck in the paint.
  • Mask the mesh, any seams you want clean and the whole visor, underside included, with low-tack tape and paper.
  • Stretch the crown over the cap jig so the front panel is taut and curved the way it will be worn. Spraying a slack panel flat distorts the design when it is worn.
  • Spray one light coat of transparent base so the colour sits on the fabric instead of soaking into it.

Layer by layer

  1. 1 · Sky — 0.5 mm · 25–30 PSI

    pale sky blue — a soft wash across the top, broken by pale cloud

    Mask None on the panel itself: the mesh and the visor are already masked from the prep.

    Colour Pale sky blue — 1 part blue to 4 parts white, a drop of green so it does not drift purple

    Needle
    0.5 mm (a 0.35 mm works, it just takes longer)
    Pressure

    Passes
    3–4 light passes, building the colour
    Dry
    10 minutes, or 60–90 seconds with a heat gun on low, before the next mask goes down

    Tip Fade wet to dry and never lay one heavy coat: twill wicks paint sideways and the edge blooms.

  2. 2 · Mountains — 0.35 mm · 20–25 PSI

    slate blue — a jagged range sitting low behind the river

    Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.

    Colour Slate blue — White with blue and a touch of black, about 4 : 1 : ½

    Needle
    0.35 mm
    Pressure

    4–6 in from the panel
    Passes
    2–3 passes
    Dry

    Tip Spray away from the stencil edge, not into it, so the air does not push paint underneath.

  3. 3 · Snowcaps — 0.35 mm · 20–25 PSI

    snow white — peaks, ridgelines and snowfields on the range

    Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.

    Colour Snow white — Opaque white from the bottle; two thin coats cover better than one thick one

    Needle
    0.35 mm
    Pressure
    20–25 PSI

    Dry
    10 minutes before lifting the stencil

    Tip Spray away from the stencil edge, not into it, so the air does not push paint underneath.

  4. 4 · Banks — 0.35 mm · 20–25 PSI

    sage green — sagebrush clumps and grassy banks on both sides

    Tip Spray away from the stencil edge, not into it, so the air does not push paint underneath.

  5. 5 · River — 0.35 mm · 20–25 PSI

    river teal — the current running from the mountains to the foreground

    Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.

    Colour River teal — 2 parts blue, 1 part green, a touch of white to lift it

    Needle
    0.35 mm
    Pressure
    20–25 PSI
    Distance
    4–6 in from the panel

    Tip Spray away from the stencil edge, not into it, so the air does not push paint underneath.

  6. 6 · Trout backs — 0.3 mm · 18–22 PSI

    olive green — the backs and upper flanks of both fish

    Mask The hand-cut subject stencil, inner pieces first, then the outline piece.

    Colour Olive green — 2 parts yellow, 1 part black, a drop of red to warm it

    Needle
    0.3 mm
    Pressure
    18–22 PSI
    Distance
    3–4 in from the panel
    Passes
    2–3 passes per tone, light to dark
    Dry
    10 minutes between tones

    Tip Light tones first: a light colour over a dark one needs many coats, a dark one over a light one needs two.

  9. 9 · Spots and detail — 0.35 mm · 20–25 PSI

    charcoal — spots, eyes, mouths and fin edges

    Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.

    Colour Charcoal — 1 part white to 3 parts black, a drop of blue

    Needle
    0.35 mm

Step by step

  1. Mask everything below the horizon and spray pale sky blue across the top. Start around 20 PSI, 0.3 mm needle, 15 cm away; treat these as a starting point and adjust to your paint.

  2. Cut a jagged ridge mask and fill the mountains with slate blue at 18 PSI, 0.3 mm needle, about 10 cm, darker at the base.

  3. Keep the ridge mask on and add snow white to the peaks and snowfields at 15 PSI, 0.2 mm needle, 8 cm, in short dry passes.

  4. Mask the river channel and spray sage green brush and grass on both banks at 18 PSI, 0.3 mm needle, 10 cm, stippling for texture.

  5. Mask the banks and fill the current with river teal at 20 PSI, 0.3 mm needle, 12 cm, deepening it toward the foreground.

  6. Place both trout masks and spray olive green over the backs and upper flanks at 18 PSI, 0.3 mm needle, 10 cm.

  7. Shift to the belly masks and lay golden cream on lower sides, fins and tails at 16 PSI, 0.3 mm needle, 10 cm.

  8. Spray the rose pink lateral band and gill plates freehand along a loose shield at 15 PSI, 0.2 mm needle, 6 cm, keeping the edges soft.

  9. Add charcoal spots, eyes, mouths and fin edges at 12 PSI, 0.2 mm needle, 3 to 4 cm, one dot at a time.

  10. Finish with snow white riffles, foam lines and eye glints at 12 PSI, 0.2 mm needle, 4 cm.

  11. Let the panel cure for at least 24 hours at room temperature before handling it.

  12. Seal with two thin coats of clear topcoat, 15 minutes apart, then heat set following your paint maker's directions.

Cure

  • Heat set at 300°F / 150°C. Water-based textile paint is not wash-fast until it is heat set.
  • Cap press: 3–5 minutes with a teflon sheet over the design.
  • Or heat gun: 2–3 minutes per panel, keeping it moving 2–3 in off the fabric so it does not scorch.
  • If you have neither, air cure for 72 hours before the cap touches water.

Seal

  • Two light coats of matte fabric sealer, UV-resistant, from 8–10 in, 15 minutes apart.
  • Leave it 24 hours before the cap is worn.
  • Never a gloss sealer on cotton twill: it shines, cracks along the creases and looks like a sticker.

Clean-up

  • Flush the brush with water, then airbrush cleaner, until it sprays clear.
  • Strip the needle and wipe it toward the tip, never away from it.
  • Never soak the brush body overnight.

Common mistakes

  • Hard-edged pink stripes look pasted on. Spray the band freehand from close in and let it fade at both edges.
  • Spraying charcoal too wet makes spots bleed into blobs. Drop the pressure and pull the trigger back only a touch.
  • Skipping the cure before sealing traps solvent and clouds the colours. Give the paint a full day first.
  • Overworking the riffles flattens the water. Add white last, in a few quick strokes, then stop.

Tips

  • Make the spots uneven in size and spacing; real rainbows never line them up.
  • Keep the rose pink band slightly wider near the gill plate and thinner toward the tail.
  • Leave a few gaps of sky blue in the slate mountains so the range reads as distant.
  • Test every colour on a scrap first, especially snow white over teal, which can turn chalky.
