Splashline Rainbow Trout Trucker Hat

by @dekasso

Half out of the water, all in.

A rainbow trout striking at the surface for a small insect, in rose pink, olive and deep teal, a compact river scene for days on the water.

A rainbow trout breaks the surface after a small winged insect, white spray flying off its head. The fish wears olive, golden yellow and a rose pink band over deep teal water and moss green stones.

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.

    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.

    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 launches up through the waterline, jaw open, eyes on a small winged insect hovering just out of reach. Below it the pool drops into deep teal, with moss green stones on the bottom. White spray hangs in the air over its head.

Wear it to the river, the boat ramp or the diner after. The pink band on the fish catches the eye first, then the splash, and people tend to lean in to find the insect.

Soft masking at the waterline matters most here. Lift the stencil edge slightly so the aqua blue band fades into the deep teal instead of meeting it in a hard line, and the fish will look like it is truly leaving the water.

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

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

  1. Pool
  2. Surface light
  3. Stones
  4. Back and head
  5. Belly
  6. Flank band
  7. Spots and detail
  8. Splash

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

  • Aqua blue

    Primary blue, a drop of white to lighten it, a drop of black to deepen it; build it in thin coats

  • Moss green

    2 parts yellow, 1 part green, a drop of black to deaden it

  • Olive

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

  • Golden yellow

    Mix by eye against the photograph; test on the card first

  • 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

  • White

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

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 · Pool — 0.5 mm · 25–30 PSI

    deep teal — the underwater body of water below the surface line, darkening toward the bottom

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

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

  2. 2 · Surface light — 0.35 mm · 20–25 PSI

    aqua blue — the bright band along the waterline and light falling through the water

    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 · Stones — 0.35 mm · 20–25 PSI

    moss green — rounded rocks resting on the bottom of the pool

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

    Colour Moss green — 2 parts yellow, 1 part green, a drop of black to deaden it

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

  4. 4 · Back and head — 0.35 mm · 20–25 PSI

    olive — the trout's back, crown and upper fins

    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

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

  5. 5 · Belly — 0.35 mm · 20–25 PSI

    golden yellow — the lower flank and belly as the fish turns upward

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

    Colour Golden yellow — Mix by eye against the photograph; test on the card first

  6. 6 · Flank band — 0.35 mm · 20–25 PSI

    rose pink — the wide pink band along the side and the gill plate

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

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

    Needle
    0.35 mm
    Pressure
    20–25 PSI
    Distance

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

  7. 7 · Spots and detail — 0.3 mm · 18–22 PSI

    black — spots on back and tail, the eye, fin edges and the insect's body

    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
    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.

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

    white — the spray bursting over the head, water highlights and the insect's wings

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

    Colour 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 outer edge of the scene and the trout silhouette. Spray deep teal for the pool, heavier toward the bottom. Start around 20 PSI, 0.5 mm needle, 15 cm away; treat these as a starting point.

  2. Keep the trout mask on. Lift the waterline stencil a few millimetres and mist aqua blue along the surface band and in soft shafts below it. Around 18 PSI, 0.35 mm needle, 10–12 cm.

  3. Place the stone mask at the bottom of the pool. Spray moss green, letting the tops of the rocks stay lighter. Around 18 PSI, 0.35 mm needle, 8–10 cm.

  4. Remove the trout mask and cover the water. Spray olive across the back, crown and upper fins, fading downward. Around 18 PSI, 0.35 mm needle, 8–10 cm.

  5. Mask the back and spray golden yellow on the lower flank and belly, blending up into the olive. Around 16 PSI, 0.35 mm needle, 8 cm.

  6. Lay the flank band stencil and spray rose pink along the side and over the gill plate, softest at the edges. Around 15 PSI, 0.2–0.35 mm needle, 6–8 cm.

  7. Use the spot and detail stencil for black: spots on back and tail, the eye, fin edges and the insect's body. Around 12–15 PSI, 0.2 mm needle, 3–5 cm.

  8. Finish with white: the splash over the head, glints on the water and fish, and the insect's wings. Around 12 PSI, 0.2 mm needle, 3–5 cm, building in short bursts.

  9. Let the paint dry fully, then heat-set or cure as your paint system directs. Seal with the clear coat it recommends and let it rest a day before wear.

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 line at the waterline: lift the stencil edge slightly and mist the aqua blue so it fades into the teal.
  • Muddy flank: let the golden yellow dry before adding rose pink, or the two will mix into a dull orange.
  • Paint creeping under masks: press stencil edges flat and use light passes instead of one wet coat.
  • Losing the insect in the background: give it a clean patch of cap colour around it and keep the splash away from it.

Tips

  • Test every colour on scrap first; rose pink over olive shifts quickly, so check the blend before touching the fish.
  • Keep the black spots small and uneven in size. Evenly sized spots make the trout look stamped rather than alive.
  • Spray the white splash last and sparingly. A few sharp droplets read as motion better than one large cloud.
  • Drop pressure for the insect so the wings stay crisp at that tiny scale.
