Cobblestone Rainbow Trout Trucker Hat

by @dekasso

Holding steady over the cobbles.

A rainbow trout over a cobbled streambed in olive green, rose red and sky blue, a painterly wraparound panel for a trucker hat.

A rainbow trout holds over a bed of rounded stream cobbles in clear blue water. Olive green, rose red and cream white paint the fish against slate grey and umber stones.

  • Rainbow trout with a rose red stripe
  • Rounded cobbles in slate grey and umber
  • Sky blue water with pale glints
  • Ochre yellow fins and fallen leaves
  • Eight colours in a painterly wraparound panel

The cap

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

    $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

    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

A rainbow trout noses into the current, mouth just open. Its back is olive and peppered with black spots, the stripe runs rose red from gill to tail, and the belly is cream. Below it, a whole streambed of round grey and brown stones, with a few yellow leaves caught between them and blue water glinting overhead.

Wear it to the river, the boat ramp or the coffee line. From across the parking lot it reads as a bright fish on blue. Up close, people start counting the stones.

Soft edges on the rose red stripe make the fish. Feather the band so it fades into the olive above and the cream below, then drop the black spots last so they sit on top of every colour.

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 4 hours at the bench, plus curing8 layersYou'll need an airbrush, a cap jig and 8 colours

The palette

  • Sky blue
  • Slate grey
  • Umber brown
  • Olive green
  • Rose red
  • Cream white
  • Black
  • Ochre yellow

The layers

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

  1. Water
  2. Stones
  3. Stone shading
  4. Trout back
  5. Stripe
  6. Belly and glints
  7. Spots and outlines
  8. Accents

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

  • Slate grey

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

  • Umber brown

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

  • Olive green

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

  • Rose red

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

  • Cream white

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

  • Black

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

  • Ochre yellow

    2 parts yellow, 1 part brown, a drop of black

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

    sky blue — a bright wash across the top with pale ripples running through it

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

    Colour 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
    25–30 PSI
    Distance
    6–8 in from the panel
    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 · Stones — 0.35 mm · 20–25 PSI

    slate grey — rounded cobbles filling the streambed under the fish

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

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

    Needle
    0.35 mm
    Pressure
    20–25 PSI
    Distance
    4–6 in from the panel
    Passes
    2–3 passes
    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.

  3. 3 · Stone shading — 0.35 mm · 20–25 PSI

    umber brown — warm undersides of the cobbles and the gaps between them

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

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

    Needle
    0.35 mm
    Pressure
    20–25 PSI
    Distance
    4–6 in from the panel
    Passes
    2–3 passes
    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 · Trout back — 0.3 mm · 18–22 PSI

    olive green — the back and upper flanks of the trout

    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.

  5. 5 · Stripe — 0.35 mm · 20–25 PSI

    rose red — the lateral band and the blush on the gill plate

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

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

    Needle
    0.35 mm

    10 minutes before lifting the stencil

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

  6. 6 · Belly and glints — 0.35 mm · 20–25 PSI

    cream white — the belly, the tops of the stones and glints in the water

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

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

    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.

  7. 7 · Spots and outlines — 0.35 mm · 20–25 PSI

    black — the spots, the eye, the mouth line and the deepest shadows

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

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

    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.

  8. 8 · Accents — 0.2–0.3 mm · 12–15 PSI

    ochre yellow — the fins and a few scattered leaves on the bottom

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

    Colour Ochre yellow — 2 parts yellow, 1 part brown, a drop of black

    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. Clean the panel, let it dry, and tape off everything outside the artwork. All settings below are typical starting points; test on scrap and adjust to your paint and airbrush.

  2. Water: no mask. Spray sky blue across the top in loose passes at 20 PSI, 0.35 mm needle, 15 cm away, leaving a few streaks lighter for ripples.

  3. Stones: lay the cobble mask and fill with slate grey at 18 PSI, 0.35 mm needle, about 10 cm away. Keep the coat even so the stones read as one bed.

  4. Stone shading: keep the cobble mask on and mist umber brown into the lower edge of each stone and the gaps at 15 PSI, 0.2 mm needle, 5 cm away.

  5. Trout back: place the trout silhouette mask, protect the belly with a strip, and spray olive green over the back and upper flanks at 18 PSI, 0.35 mm needle, 8 cm away.

  6. Stripe: lift the strip, add the stripe mask, and spray rose red along the lateral band and gill plate at 15 PSI, 0.2 mm needle, 5 cm away, feathering both edges.

  7. Belly and glints: spray cream white on the belly, then freehand small highlights on stone tops and ripples at 12 PSI, 0.2 mm needle, 3 to 4 cm away.

  8. Spots and outlines: with the detail stencil, place black spots, the eye and the mouth line at 12 PSI, 0.2 mm needle, 2 to 3 cm away. Deepen the darkest stone gaps lightly.

  9. Accents: spray ochre yellow into the fins and a few leaf shapes between the stones at 12 PSI, 0.2 mm needle, 3 cm away.

  10. Remove all masks and tape slowly. Let the paint cure for 24 hours at room temperature, or heat set if your paint calls for it.

  11. Seal with two thin coats of a matte fabric sealer, letting each dry fully before the next.

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 the rose red stripe with a hard edge. Hold back a little and feather so it melts into olive and cream.
  • Overloading umber brown until the stones turn muddy. Mist in short passes and stop early.
  • Pulling masks while paint is wet, which smears the cobble outlines. Wait until it is dry to the touch.
  • Sealing too heavily and dulling the glints. Two thin coats keep the cream highlights bright.

Tips

  • Lay the stone mask with cobbles of different sizes; mixed shapes look like a real streambed.
  • Leave tiny unpainted gaps in the blue wash and you get ripples without adding another layer.
  • Check the trout's eye before anything else on the spot layer. A sharp eye carries the whole fish.
  • Thin your black slightly so the spots stay crisp and do not spit.
