Henry's Fork Rainbow Trout Hat

by @john

Five rainbows holding under the pines.

A split-view river scene of five rainbow trout below a pine shoreline, in teal, olive and rose pink, for days on the water.

Five rainbow trout hold in a clear teal river beneath pine-lined banks and a pale mountain. The scene is coloured in turquoise, olive and forest green, with a rose pink stripe on every fish.

  • Five rainbow trout in one river scene
  • Split view above and below the waterline
  • Rose pink stripes on olive backs
  • Pine banks and a pale mountain
  • Teal water over grey river stones

The cap

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

    What it sits on
    On a natural cotton twill front.
    Durability and care

    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

Five rainbow trout swim through teal water, each one wearing a rose pink stripe and a cream belly. Above the waterline, dark pines lean in from both banks and a pale mountain sits in the sky. Olive weeds sway up from a bed of grey stones.

Wear it on the drive to the river, at the boat ramp, or in line for coffee after the evening hatch. People see the fish first, then catch the forest and sky above them and lean in for a second look.

The rose pink stripe is what makes these fish read as rainbows. Keep it a thin, soft band along the flank, laid over the olive back and stopping short of the cream belly, so each trout keeps its shape.

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.

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

  • Sky blue

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

  • Forest green

    2 parts green, 1 part black, a drop of blue to cool it

  • Teal

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

  • Turquoise

    1 part blue, 1 part green, 2 parts white; a drop of yellow if it looks too cold

  • Olive

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

  • Slate grey

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

  • 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

  • Cream

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

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

    sky blue — a pale sky and a soft distant mountain above the waterline

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

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

    Needle
    0.35 mm
    Pressure

    3–4 in from the panel
    Passes
    2–3 passes per tone, light to dark

    rose pink — the lateral stripe and gill plate on each fish

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

    Mask None: freehand, with a shield card held against any hard edge.

    Colour Cream — White with a drop of yellow and the smallest touch of brown

    Needle
    0.2–0.3 mm
    Pressure
    12–15 PSI
    Distance
    1–2 in from the panel

Step by step

  1. Mask the upper sky band and spray sky blue at about 20 PSI, 0.3 mm needle, 15 cm away, fading lighter toward the waterline. Treat all settings here as a starting point and adjust for your paint.

  2. Lay the pine mask along both banks and the far shore. Spray forest green at about 18 PSI, 0.3 mm needle, 10 cm away, building darker at the tree bases.

  3. Cover the sky and pines, then spray the river body in teal at about 22 PSI, 0.5 mm needle, 15–20 cm away, heavier toward the bottom for depth.

  4. Mask a thin band at the waterline and mist turquoise at about 18 PSI, 0.3 mm needle, 15 cm away, letting it bleed softly into the teal below.

  5. Use a weed stencil along the bottom and spray olive at about 15 PSI, 0.2 mm needle, 5–8 cm away, flicking upward for each stem.

  6. Mask the pebble shapes and dab slate grey at about 15 PSI, 0.3 mm needle, 8 cm away, leaving darker edges where stones meet.

  7. Place the five trout masks and spray olive on backs and fins at about 15 PSI, 0.2 mm needle, 6 cm away, keeping the belly area clear.

  8. Use a stripe mask on each fish and spray rose pink at about 12 PSI, 0.2 mm needle, 5 cm away, running a thin band along the flank and over the gill plate.

  9. Spray charcoal spots through a dot stencil, or freehand, at about 12 PSI, 0.2 mm needle, 3–4 cm away. Add the pupils last.

  10. Spray cream on bellies, eye rings and surface glints at about 12 PSI, 0.2 mm needle, 4–5 cm away. Keep it crisp.

  11. Let the paint cure at least 24 hours at room temperature, then heat set or seal 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

  • Spraying rose pink too wide turns the fish pink all over. Keep pressure low and stay close for a narrow stripe.
  • Letting olive weeds cover the fish bellies muddies them. Mask the trout before the weed layer or spray weeds first.
  • Heavy charcoal spots can blot and spread. Use low pressure and short bursts, letting each dot dry.
  • Removing masks before paint sets lifts edges. Wait until each layer is dry to the touch.

Tips

  • Test each colour on a scrap panel first, especially rose pink over olive, since layered colours shift.
  • Build the teal in two or three light passes for a clean fade into depth.
  • Keep the waterline perfectly level across the design; a tilted horizon breaks the split-view effect.
  • Vary the spot size slightly from fish to fish so the five trout feel alive, not stamped.
