Streambed Brown Trout Trucker Hat

by @dekasso

Holding in the current, light pouring down

A realistic brown trout over pebbles and weed in green water, with light shafts from the surface, for days spent on the river.

A brown trout holds steady over a pebbled streambed, beneath rippling green water and slanting shafts of light. It is coloured in deep forest green, golden yellow and olive brown, with black spots and cream highlights.

  • Golden brown trout with black spots
  • Pale aqua light shafts through green water
  • Slate grey pebbles and moss green weed
  • Rippled surface bands across the top
  • Eight stencil layers, background to highlight

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.

    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.

    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 brown trout hangs in green water, fins spread, nose into the flow. Shafts of pale light slant down from a rippled surface. Below it, grey stones and waving moss-green weed fill the streambed.

Wear it on the bank, at the fly shop or on the drive home. From across the room it reads as one golden fish in a pool of green. Up close, people notice the black spots and the light on the stones.

Light shafts carry this piece. Lay the pale aqua in thin, angled passes that fade before they reach the stones, so the water feels deep rather than striped.

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

  • Deep forest green
  • Pale aqua
  • Slate grey
  • Moss green
  • Golden yellow
  • Olive brown
  • Black
  • Cream

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. Light
  3. Streambed
  4. Weed
  5. Trout body
  6. Back shading
  7. Spots
  8. 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 forest green

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

  • Pale aqua

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

  • Slate grey

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

  • Moss green

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

  • Golden yellow

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

  • Olive brown

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

  • Black

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

  • 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 · Water — 0.5 mm · 25–30 PSI

    deep forest green — the full underwater background, darkest along the bottom and edges

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

    Colour Deep forest green — 2 parts green, 1 part black, a drop of blue to cool it

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

    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 · Light — 0.35 mm · 20–25 PSI

    pale aqua — rippling surface bands across the top and slanted shafts of light falling through the water

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

    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 · Streambed — 0.35 mm · 20–25 PSI

    slate grey — rounded pebbles and stones along the bottom

    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

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

  4. 4 · Weed — 0.35 mm · 20–25 PSI

    moss green — waving blades of weed rising from the stones on both sides

    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.

  5. 5 · Trout body — 0.3 mm · 18–22 PSI

    golden yellow — the trout's flank, belly, head and fins

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

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

    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.

  6. 6 · Back shading — 0.35 mm · 20–25 PSI

    olive brown — the dark back, top of the head and the fin edges

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

    Colour Olive brown — 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.

  7. 7 · Spots — 0.35 mm · 20–25 PSI

    black — spots across the flank and gill plate, the eye and fin outlines

    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

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

    cream — belly sheen, fin tips, the glint in the eye and light catching the pebbles

    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

    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, mask everything outside the art area, and lay deep forest green over the whole background. Start around 20–25 PSI, 0.5 mm needle, 15–20 cm away; these are starting points. Darken the bottom and edges with extra passes.

  2. Cut the surface ripple and light-shaft mask. Spray pale aqua at about 15–18 PSI, 0.3 mm needle, 10–15 cm. Fade each shaft toward the bottom with lighter, quicker passes.

  3. Mask the pebble shapes along the bottom and spray slate grey at around 18–20 PSI, 0.3 mm needle, 10 cm. Leave the darker green showing between stones.

  4. Use a weed-blade stencil and spray moss green at 15–18 PSI, 0.3 mm needle, 8–10 cm. Let a few blades overlap the pebbles.

  5. Mask the trout outline and spray golden yellow across the body, belly and fins at about 18–20 PSI, 0.3 mm needle, 10–12 cm. Build it up in two or three light coats.

  6. Keep the trout mask on and add olive brown along the back, top of the head and fin edges at 15 PSI, 0.3 mm needle, 8–10 cm. Fade it softly down into the yellow flank.

  7. Switch to a spot stencil and spray black at about 12–15 PSI, 0.2 mm needle, 5–8 cm for the spots, eye and fin outlines. Keep each spot crisp and small.

  8. Finish with cream at 12 PSI, 0.2 mm needle, 5–8 cm: belly sheen, fin tips, the eye glint and a touch of light on the top of a few pebbles.

  9. Remove all masks and let the paint cure for at least 24 hours at room temperature, or heat-set as your paint maker directs.

  10. Seal with two thin coats of a flexible fabric-safe clear coat, 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

  • Light shafts that run edge to edge look like stripes. Fade them out halfway down with lighter passes.
  • Spraying the yellow too heavily in one go causes runs on the fins. Build it in thin coats and let each flash off.
  • Black spots bleeding into fuzzy blobs. Drop the pressure, move closer and use a tightly held stencil.
  • Sealing before the paint has cured can cloud the colours. Wait the full cure time before the clear coat.

Tips

  • Spray the light shafts at a slight angle that matches the ripple direction so they look like they come from one sun.
  • Test every colour on a scrap panel first; golden yellow over dark green can shift, so check how many coats you need.
  • Vary spot size from large on the back to small toward the belly for a more natural flank.
  • Keep the cream highlights few and small; a handful of bright points does more than a wash.
