Eddyline Rainbow Trout Trucker Hat

by @dekasso

Holding in the swirl, eyes on the hatch.

A rainbow trout in green current with bubbles, two mayflies and a nymph, in olive, rose pink and deep green, for days on the water.

A rainbow trout turns through a swirl of green current, with mayflies and a nymph drifting nearby. It is coloured in deep green, olive and rose pink, with white bubbles and curling water lines.

  • Rainbow trout with a rose pink stripe
  • Swirling white current and rising bubbles
  • Two mayflies and a drifting nymph
  • Deep green and sage green water
  • Black spots across back, fins and tail

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.

    Hand airbrushed

    $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

A rainbow trout swings through deep green water, mouth open, rose pink stripe bright down its flank. White current curls over it and loops beneath. Bubbles rise all around, and two tan mayflies and a nymph drift at the edges.

Wear it to the river, the fly shop or the tailgate after. The trout reads from across a parking lot, and the bugs reward anyone who leans in for a closer look.

Rose pink over olive is the part to get right. Build the stripe in thin, misted passes so the edges melt into the green back instead of sitting on top as a hard band.

What arrives

  • A care card
  • On a hand airbrushed hat, a numbered tag naming the water it was painted from, when the design names one

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.

  1. Water
  2. Shallows
  3. Current
  4. Bubbles
  5. Trout base
  6. Back and fins
  7. Stripe
  8. Insects
  9. Spots and eye
  10. 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 green

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

  • Sage green

    2 parts green, 1 part white, a drop of black to dull it

  • White

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

  • Silver gray

    Metallic silver, or 6 parts white to 1 part black in a pearl or metallic medium

  • Olive

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

  • Rose pink

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

  • Tan

    3 parts white, 2 parts yellow, 1 part brown

  • 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 green — a fill across the whole design, darker at the edges and lifting toward the middle

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

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

    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 · Shallows — 0.35 mm · 20–25 PSI

    sage green — a soft glow behind the trout and through the lower water

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

    Colour Sage green — 2 parts green, 1 part white, a drop of black to dull it

    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 · Current — 0.35 mm · 20–25 PSI

    white — curling surface line along the top and swirls looping under and around the fish

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

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

    Needle
    0.35 mm

    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 · Bubbles — 0.35 mm · 20–25 PSI

    white — rings of small and large bubbles scattered through the water

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

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

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

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

    silver gray — the full body shape, belly and fins

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

    Colour Silver gray — Metallic silver, or 6 parts white to 1 part black in a pearl or metallic medium

    Needle
    0.3 mm
    Pressure

    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.

  6. 6 · Back and fins — 0.35 mm · 20–25 PSI

    olive — the upper body, dorsal fin and tail

    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

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

    Colour Tan — 3 parts white, 2 parts yellow, 1 part brown

    Needle

    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 design area and wipe the surface clean. All settings below are a starting point; test on scrap first.

  2. Deep green water: open fill, 20–25 PSI, 0.5 mm needle, 15–20 cm away. Heavier at the edges, lighter toward the centre.

  3. Sage green shallows: freehand glow behind where the trout will sit, 18 PSI, 0.35 mm needle, 10–15 cm.

  4. White current: cut swirl stencil for the surface line and loops, 18–20 PSI, 0.35 mm needle, 5–8 cm for crisp curls.

  5. White bubbles: circle template, 15 PSI, 0.2 mm needle, 3–5 cm. Spray rings, not solid dots.

  6. Silver gray trout base: full body stencil including fins, 20 PSI, 0.35 mm needle, 8–10 cm, even coverage.

  7. Olive back and fins: keep the body mask on, 18 PSI, 0.35 mm needle, 8–10 cm, fading down toward the flank.

  8. Rose pink stripe and gill: freehand along the flank, 15 PSI, 0.2 mm needle, 5–8 cm, in several light passes.

  9. Tan insects: small mayfly and nymph stencils, 15 PSI, 0.2 mm needle, 3–5 cm.

  10. Black spots, eye and legs: dot stencil or freehand, 12–15 PSI, 0.2 mm needle, 2–4 cm.

  11. White highlights: freehand glints on the eye, belly edge and bubble rims, 12 PSI, 0.2 mm needle, 2–3 cm.

  12. Cure: let the paint dry 24 hours, then heat-set following the paint maker's guidance.

  13. Seal: two light coats of fabric-safe matte sealer, 15–20 cm away, drying between coats.

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-edged pink stripe: too much pressure or too close. Drop to 15 PSI and build in thin passes.
  • Muddy olive over green water: let the silver gray base dry fully before the olive goes on.
  • Spidering on fine black spots: paint too thin or pressure too high. Thicken slightly and lower PSI.
  • Lifting the body mask too early: wait until the olive is touch-dry before peeling.

Tips

  • Spray the white current before the trout so the swirls tuck behind the body rather than across it.
  • Keep the trout's spots uneven in size and spacing; a grid of identical dots looks stamped.
  • Leave a thin unpainted gap between bubble rims and their centres so the green shows through.
  • Warm the rose pink slightly toward the gill plate so the face carries more colour than the tail.
