Sunlit Stonefly Nymph Trucker Hat

by @dekasso

Holding tight where the light reaches bottom

A stonefly nymph on mossy streambed stones under slanting sun rays, painted in deep pine, moss and pale cream for days on moving water.

A stonefly nymph clings to mossy boulders on the streambed while sun shafts slant down through the water. It is coloured in deep pine, moss and olive brown, with pale cream light falling across the scene.

  • Pale cream sun rays through deep water
  • Deep pine, moss and olive brown palette
  • Segmented body, banded legs, twin tails

The cap

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

One size per cap. Run a tape around your head just above the ears, keeping it level — anything inside the range above will close on it.

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 stonefly nymph spreads its six legs across a mossy boulder, antennae forward, twin tails trailing behind. Pale cream rays fan down through deep pine water and catch the ridges of its back. The stones below glow moss and olive brown.

Wear it to the riffle, the fly shop or the tailgate after. The palette sits quietly with river clothes, and anyone who has turned over a rock will know the bug on sight.

Sun shafts make or break this piece. Keep the pale cream soft and thin, fading out before the rays reach the boulders, so the light reads as water and not as stripes.

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

IntermediateAbout 3½ hours at the bench, plus curing7 layersYou'll need an airbrush, a cap jig and 6 colours

The palette

  • Deep pine
  • Sage mist
  • Moss
  • Olive brown
  • Khaki
  • Pale cream

The layers

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

  1. Deep water
  2. Water glow
  3. Boulders
  4. Rock shadows
  5. Nymph body
  6. Nymph markings
  7. Sun shafts

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 pine

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

  • Sage mist

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

  • Moss

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

  • Olive brown

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

  • Khaki

    4 parts white, 1 part yellow, a drop of brown; a drop of green for khaki

  • Pale 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 · Deep water — 0.5 mm · 25–30 PSI

    deep pine — a dark fade low and along both sides

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

    Colour Deep pine — 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

    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 · Water glow — 0.35 mm · 20–25 PSI

    sage mist — a lighter haze opening toward the top

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

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

    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 · Boulders — 0.35 mm · 20–25 PSI

    moss — rounded, mossy stones across the lower half

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

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

    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 · Rock shadows — 0.35 mm · 20–25 PSI

    olive brown — crevices, undersides and the gaps between stones

    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

    Needle
    0.35 mm
    Pressure
    20–25 PSI

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

  5. 5 · Nymph body — 0.35 mm · 20–25 PSI

    olive brown — the segmented abdomen, thorax, six legs, antennae and twin tails

    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

    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.

  6. 6 · Nymph markings — 0.3 mm · 18–22 PSI

    khaki — wing pads, leg bands, segment edges and head pattern

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

    Colour Khaki — 4 parts white, 1 part yellow, a drop of brown; a drop of green for khaki

    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.

  7. 7 · Sun shafts — 0.2–0.3 mm · 12–15 PSI

    pale cream — rays fanning down from the top, glints on moss and the nymph's back

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

    Colour Pale cream — White with a drop of yellow and the smallest touch of brown

    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 artwork area and spray deep pine around the bottom and sides as a soft fade. Start near 20 PSI, 0.3 mm needle, 15 cm distance; these are starting points, adjust to your paint.

  2. Spray sage mist across the upper middle so the water lightens toward the top. Keep 18–20 PSI and a 15–20 cm distance for a smooth blend.

  3. Cut a boulder mask with rounded tops and lay moss over the lower half. Try 20 PSI, 0.3 mm needle, about 10 cm.

  4. Shade the crevices and stone undersides with olive brown, freehand along the mask edges. Drop to about 15 PSI, 0.2 mm needle, 5 cm.

  5. Place the nymph stencil and fill the body, legs, antennae and tails with olive brown. Use roughly 15 PSI, 0.2 mm needle, 5–8 cm.

  6. Mask the segment edges, wing pads and leg bands and add khaki. Work close, around 12–15 PSI, 0.2 mm needle, 3–5 cm.

  7. Lay a ray mask fanning from the top and dust pale cream in light passes. Start near 15 PSI, 0.2 mm needle, 15–20 cm, then add small glints on the moss and the nymph's back up close.

  8. Let the paint dry fully, heat-set it per your paint's directions, then seal it as your paint maker recommends and let it cure 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-edged sun rays look like stripes. Lift the mask slightly off the surface for a soft edge.
  • Muddy rocks from too much olive brown. Shade only the undersides and gaps, then stop.
  • Legs that blur into the moss. Keep the moss lighter where the legs cross it.
  • Sealing too soon traps solvent and dulls the colours. Wait the full dry time first.

Tips

  • Cut the boulder mask with a slightly uneven edge so the moss looks lumpy and alive.
  • Spray the sun rays last and from farther back; several faint passes beat one heavy one.
  • Leave a thin dark line between the nymph's legs and the stone so it reads as clinging, not floating.
  • Test the khaki over olive brown on scrap first to check it shows without going chalky.
