South Platte Rainbow Trout Trucker

by @sunny

Two fish holding steady in the current.

A pair of rainbow trout over pebbles and weeds in teal water, a realistic underwater scene for days on the river.

Two rainbow trout swim one above the other through clear green water over a pebble bed. Deep teal water, rose pink stripes, olive backs and a scatter of black spots carry the whole picture.

  • Umber pebbles and olive weed blades
  • Rising bubbles under a rippled surface

The cap

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

Two finishes

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

    $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 hang in the current, one high, one low, noses pointed the same way. Rose pink runs down each flank. Bubbles drift up toward a rippled surface, and olive weeds sway out of a bed of umber stones.

It reads well from across a parking lot at the put-in and holds up close at the tailgate. People see the fish first, then the spots, then the little bubbles. Wear it to the river, the fly shop or the diner after.

Black spotting is where the trout come alive. Keep the spots small and uneven, heavier on the back and tail, lighter toward the belly, so the fish look like fish and not polka dots.

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.

Make it yourself

A hat-painting bench with a blank cap, stencils and an airbrush

AdvancedAbout 4½ hours at the bench, plus curing9 layersYou'll need an airbrush, a cap jig and 7 colours

The palette

  • Deep teal
  • Sea green
  • Umber
  • Olive
  • Pearl white
  • Rose pink
  • Black

The layers

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

  1. Water
  2. Light band
  3. Riverbed
  4. Weeds
  5. Flanks
  6. Backs
  7. Stripes
  8. Spots
  9. 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

  • Deep teal

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

  • Sea green

    1 part yellow to 1 part blue; more yellow for a warm green, more blue for a cool one

  • Umber

    Equal parts red, yellow and blue, then a drop of black to deepen it; or burnt umber straight from the bottle

  • Olive

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

  • Pearl white

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

  • Rose pink

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

  • Black

    Black from the bottle, sprayed in light passes; a heavy coat bleeds

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 · Water — 0.5 mm · 25–30 PSI

    deep teal — a full fade from the wavy surface line down to the riverbed

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

    olive — upper bodies, dorsal fins and tails of both trout

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

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

  8. 8 · Spots — 0.3 mm · 18–22 PSI

    black — scattered spots, eyes and fin edges

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

    Colour Black — Black from the bottle, sprayed in light passes; a heavy coat bleeds

    Needle
    0.3 mm

    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 · Highlights — 0.2–0.3 mm · 12–15 PSI

    pearl white — rising bubbles, the ripple line and glints on the scales

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

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

    Needle
    0.2–0.3 mm
    Pressure
    12–15 PSI
    Distance
    1–2 in from the panel
    Passes
    Freehand, in short controlled strokes
    Dry
    10 minutes, then check it before you cure

    Tip Low pressure, close in and moving: stop the stroke before you release the trigger.

Step by step

  1. Mask the full panel outline. Spray deep teal at about 20 PSI, 0.3 mm needle, 15 cm away, darkest at the bottom and lighter toward the top. Treat all settings here as a starting point.

  2. Keep the outline mask. Mist sea green at 18 PSI, 0.3 mm needle, 15–20 cm away, across the upper water and the open space between the fish.

  3. Cut a pebble mask along the bottom edge. Spray umber at 18 PSI, 0.3 mm needle, 10 cm away, leaving soft centres so each stone looks rounded.

  4. Use a blade-shaped stencil for the weeds. Spray olive at 15 PSI, 0.2 mm needle, 5–8 cm away, flicking each stroke upward to a fine tip.

  5. Mask both trout silhouettes open. Spray pearl white at 15 PSI, 0.2 mm needle, 10 cm away across bellies and lower flanks.

  6. Shield the bellies with a curved mask. Spray olive at 15 PSI, 0.2 mm needle, 8 cm away over backs, dorsal fins and tails, fading into the white.

  7. Mask a narrow band along each flank and the gill plates. Spray rose pink at 12 PSI, 0.2 mm needle, 6–8 cm away, soft at the edges.

  8. Freehand or use a dot stencil for spots, eyes and fin edges. Spray black at 10–12 PSI, 0.2 mm needle, 3–5 cm away in short bursts.

  9. Finish with pearl white at 10 PSI, 0.2 mm needle, 3–5 cm away for bubbles, the ripple line and a few scale glints.

  10. Let the panel dry fully, heat-set or cure as your paint maker directs, then seal following the same instructions.

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

  • Spotting the fish evenly all over. Cluster spots on the back and tail and thin them toward the belly.
  • Hard edges on the pink stripe. Lower the pressure and pull back a little so it blends into the flank.
  • Rushing layers while wet. Let each coat flash dry or the colours bleed into mud.
  • Overspraying white highlights. A few sharp glints read brighter than a haze.

Tips

  • Test each colour on a scrap first; teal and olive can look alike until they dry.
  • Spray the pink stripe slightly wider than you want and let the olive edge it back.
  • Vary bubble sizes and keep most of them rising in loose lines from the weeds and the fish mouths.
  • Turn the work as you go so the fish backs stay curved and natural.
