Streambed Stonefly Nymph Trucker Hat

by @dekasso

Down where the trout look first.

A stonefly nymph on a sunlit streambed in teal, slate and tan, a realistic underwater scene for the front of a trucker hat.

A stonefly nymph crawls over a smooth rounded stone on a river bottom, lit by shafts of sun through the water. Deep teal and aqua water sit above slate blue cobbles, olive drab stone and a warm tan nymph.

  • Stonefly nymph on a rounded river stone
  • Pale cream sun shafts through teal water
  • Slate blue and olive cobble streambed
  • Eight layers, background to highlight
  • Warm tan nymph with legs and antennae

The cap

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

    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 stonefly nymph grips the top of a round stone, antennae forward, tails trailing. Light falls through the surface in pale cream shafts. Below, the bottom is a crowd of slate blue and olive cobbles, with a dark ledge rising on the right.

It reads as cool water from across a parking lot and as a bug study up close. Wear it on a gravel bar at dawn, at the fly shop counter, or anywhere someone turns over rocks to see what lives under them.

Light shafts in pale cream decide whether the water looks deep. Keep them thin at the surface, wider as they fall, and fade them out before they reach the stones so the nymph stays the brightest thing in the frame.

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 7 colours

The palette

  • Deep teal
  • Aqua
  • Pale cream
  • Slate blue
  • Olive drab
  • Burnt umber
  • Warm tan

The layers

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

  1. Open water
  2. Upper water
  3. Light shafts
  4. Cobbles
  5. Boulder
  6. Shadows
  7. Nymph
  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 teal

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

  • Aqua

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

  • Pale cream

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

  • Slate blue

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

  • Olive drab

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

  • Burnt umber

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

  • Warm tan

    3 parts white, 2 parts yellow, 1 part 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.

    olive drab — the big rounded stone in the centre and warm cobble tops

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

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

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

    pale cream — surface ripples, glints on stone tops, the shine on the nymph's back

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

Step by step

  1. Mask the outline of the scene and fill the open water with deep teal. As a starting point, try 20 PSI, a 0.3 mm needle and about 15 cm distance, in light even passes.

  2. Without a mask, fade aqua across the top third so the water lightens toward the surface. Start near 18 PSI, 0.3 mm needle, 15–20 cm, and blend the lower edge into the teal.

  3. Lay a thin strip mask for each light shaft and mist pale cream at around 15 PSI, 0.2 mm needle, 10 cm. Let each ray fade to nothing halfway down.

  4. Mask the bottom band and stipple slate blue cobbles with a circle stencil. A starting point is 18 PSI, 0.3 mm needle, 8–10 cm, varying stone size as you go.

  5. Cut a mask for the large central boulder and spray olive drab, then dust the tops of the nearer cobbles. Begin around 18 PSI, 0.3 mm needle, 10 cm.

  6. Freehand burnt umber into the gaps between stones, under the boulder and along the ledge at right. Try 15 PSI, 0.2 mm needle, 5–8 cm for crisp shadow lines.

  7. Place the nymph stencil on the boulder and fill the body, legs, antennae and tails with warm tan. Start near 15 PSI, 0.2 mm needle, 5 cm, in short bursts.

  8. Return to burnt umber at low pressure to mark the nymph's segments, wing pads and leg joints. Around 12 PSI, 0.2 mm needle, 3–5 cm is a good starting point.

  9. Finish with pale cream highlights: surface ripples, glints on stone tops and a sheen down the nymph's back. Begin at 12 PSI, 0.2 mm needle, 5 cm.

  10. Let the paint dry fully, then heat set according to your paint's instructions. Once cool, seal with a thin, even clear topcoat and let it cure before wearing.

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 straight to the stones flatten the scene. Fade each ray out well above the bottom.
  • Heavy passes of burnt umber turn the cobbles muddy. Build shadows in light coats and stop before the gaps fill solid.
  • Spraying the nymph too far away blurs the legs. Move in close, drop the pressure, and work in short bursts.
  • Sealing before the paint is fully dry can cloud the colours. Give it time to dry and heat set first.

Tips

  • Test every colour and setting on scrap first; the pressures, needles and distances here are only a place to begin.
  • Keep the nymph stencil cut clean at the legs and antennae. Thin parts lift easily, so press them down just before you spray.
  • Vary the cobble sizes and leave small gaps of teal showing between them. A bottom with breathing room reads as deeper water.
  • Spray highlights last and sparingly. A few bright glints carry more light than a wash of cream.
