Mossbank Mayfly Dun Trucker Hat
by @dekasso
Wings up, drying in the first light.
A realistic mayfly dun perched on moss before a bright sunburst, in amber, tan and pine green, for a day on the river.
A mayfly dun rests on a cushion of moss while a sunburst opens behind its upright wings. It is coloured in amber, sun yellow and cream light over pine and moss green, with a tan body veined in umber.
- Mayfly dun with upright veined wings
- Amber and yellow sunburst behind the insect
- Cushion of pine and moss green
- Long tan tails trailing to the right
- Cream glints on wing edges
The cap

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.

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.

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 mayfly sits on a mound of moss, wings held high and still. Behind it, a sun bursts open in amber and yellow, and the light slips through the thin wings. Long tails trail off to the right like two fine lines of thread.
Wear it to the evening hatch or the morning coffee. People see the sun first, then the insect, then the moss. It reads from across a parking lot and rewards anyone who leans in.
Umber vein lines make the wings. Lay them thin and light over the tan, so the sunburst still glows through and the wings stay clear rather than muddy.

What arrives
- The hat
- 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 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
Amber
3 parts yellow, 1 part red, a drop of black to deepen it
Sun yellow
Mix by eye against the photograph; test on the card first
Cream
White with a drop of yellow and the smallest touch of brown
Pine green
2 parts green, 1 part black, a drop of blue to cool it
Moss green
2 parts yellow, 1 part green, a drop of black to deaden it
Tan
3 parts white, 2 parts yellow, 1 part brown
Umber
Equal parts red, yellow and blue, then a drop of black to deepen it; or burnt umber straight from the bottle
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 · Glow — 0.5 mm · 25–30 PSI
amber — a soft round halo fading out into the dark edges
Mask None on the panel itself: the mesh and the visor are already masked from the prep.
Colour Amber — 3 parts yellow, 1 part red, a drop of black to deepen it
- 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 · Sunburst — 0.35 mm · 20–25 PSI
sun yellow — long rays fanning from a bright core behind the wings
Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.
Colour Sun yellow — Mix by eye against the photograph; test on the card first
- 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 · Sun core — 0.35 mm · 20–25 PSI
cream — the white-hot centre of the burst
Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.
Colour Cream — White with a drop of yellow and the smallest touch of brown
- 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 · Moss base — 0.35 mm · 20–25 PSI
pine green — a low, dark mound of moss beneath the insect
Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.
Colour Pine green — 2 parts green, 1 part black, a drop of blue to cool 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.
5 · Moss fronds — 0.35 mm · 20–25 PSI
moss green — curling tips and tufts across the mound
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
- 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 · Mayfly — 0.35 mm · 20–25 PSI
tan — segmented body, thorax, legs, upright wings and long tails
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
- 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.
7 · Detail — 0.3 mm · 18–22 PSI
umber — wing veins, body bands and shadow under the legs
Mask The hand-cut subject stencil, inner pieces first, then the outline piece.
Colour Umber — Equal parts red, yellow and blue, then a drop of black to deepen it; or burnt umber straight from the bottle
- 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 · Highlights — 0.2–0.3 mm · 12–15 PSI
cream — wing edges, glints on the back and tail tips
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
- 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
Mask everything outside an oval for the glow. Spray amber at about 20 PSI, 0.5 mm needle, 15 cm away in soft circles, letting it fade at the edge. Treat all settings here as a starting point.
Cut a ray mask with long narrow slots fanning from one point. Spray sun yellow at 20 PSI, 0.5 mm needle, 10 cm, working from the core outward so each ray tapers.
Mask a small circle at the ray centre. Spray cream at 18 PSI, 0.3 mm needle, 8 cm, building the core in two light passes.
Mask the lower band with a wavy top edge for the moss mound. Spray pine green at 22 PSI, 0.5 mm needle, 10 cm, heavier at the bottom.
Use a frond stencil with curled tips over the mound. Spray moss green at 18 PSI, 0.3 mm needle, 6 cm, shifting the stencil between passes for variety.
Mask the mayfly silhouette: body, legs, wings and tails. Spray tan at 18 PSI, 0.3 mm needle, 8 cm. Keep the wings lighter than the body so the sun shows through.
Lay a vein and band stencil over the insect. Spray umber at 15 PSI, 0.2 mm needle, 4 cm, in short controlled bursts. Add a soft shadow under the legs freehand.
Mask fine slits along wing edges, the back and tail tips. Spray cream at 15 PSI, 0.2 mm needle, 4 cm for crisp glints.
Let the paint dry fully, then heat-set following your paint maker's guidance.
Finish with a light clear topcoat suited to your paint, two thin coats, drying between each.
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
- Flooding the sun core with cream until it turns flat. Build it in light passes and stop early.
- Veins sprayed too heavy, making the wings look dark. Drop pressure and pull back a little.
- Tails lost in the dark edge. Give them a cream tip so the eye can follow them.
- Moss edge too straight. Cut the mound mask with an uneven, lumpy top line.
Tips
- Spray the sunburst before the insect so the wings sit on top of the light, not under it.
- Keep wing paint thin. A see-through tan sells the delicacy far better than a solid fill.
- Vary the moss fronds by rotating the stencil a few degrees each pass so no two tufts match.
- Test the umber vein stencil on scrap first; fine slots clog fast at close range.
