Mossy Boulder Crawl
by @dekasso
Turn the rock and there they are.
Three stonefly nymphs crawling over mossy riverbed stones under a slate-blue water fade, a realistic scene for anyone who reads a river.
Three stonefly nymphs crawl across a riverbed, picking their way past a big moss-covered boulder. The scene is coloured in moss green, ochre and stone grey under a slate-blue fade of water.
- Three stonefly nymphs on riverbed stones
- A moss-green boulder at the centre
- Slate-blue water fading across the top
- Ochre warmth on packed pebbles
- Cream glints on segments and stones
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.
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 heavy boulder sits in the middle, green with moss and flecked with ochre. Three stonefly nymphs work their way over the pebbles around it, legs splayed, tails out. Above them the water fades to a cool slate blue.
Wear it on the bank, at the fly shop counter or at the tailgate after an early morning. People who fish will lean in and name the bug. Everyone else sees a quiet patch of riverbed with something alive in it.
Masking the nymph legs is where this one lives or dies. Cut them thin and clean in the umber brown layer, then let the cream highlight catch only the edge of each segment.
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 layers
6 layers, in this order. Each mask comes off and the paint has to dry before the next one goes down.
- Water
- Riverbed
- Boulder
- Warm stones
- Nymphs
- 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
Slate blue
White with blue and a touch of black, about 4 : 1 : ½
Stone grey
4 parts white, 1 part black; a drop of blue for cool grey, a drop of brown for warm stone
Moss green
2 parts yellow, 1 part green, a drop of black to deaden it
Ochre
2 parts yellow, 1 part brown, a drop of black
Umber brown
Equal parts red, yellow and blue, then a drop of black to deepen it; or burnt umber straight from the bottle
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 · Water — 0.5 mm · 25–30 PSI
slate blue — a cool fade across the top, like light through a river
Mask None on the panel itself: the mesh and the visor are already masked from the prep.
Colour Slate blue — White with blue and a touch of black, about 4 : 1 : ½
- 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 · Riverbed — 0.35 mm · 20–25 PSI
stone grey — packed rounded pebbles filling the lower half
Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.
Colour Stone grey — 4 parts white, 1 part black; a drop of blue for cool grey, a drop of brown for warm stone
- 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 · Boulder — 0.35 mm · 20–25 PSI
moss green — the large mossy stone at the centre and moss on the pebbles
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.
4 · Warm stones — 0.35 mm · 20–25 PSI
ochre — sunlit tops of pebbles and lichen patches on the boulder
Mask Lay this layer's mylar stencil and burnish the edges flat with your thumbnail.
Colour Ochre — 2 parts yellow, 1 part brown, a drop of black
- 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 · Nymphs — 0.3 mm · 18–22 PSI
umber brown — three crawling stonefly nymphs with legs, antennae and twin tails
Mask The hand-cut subject stencil, inner pieces first, then the outline piece.
Colour Umber brown — 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.
6 · Highlights — 0.2–0.3 mm · 12–15 PSI
cream — glints on the stones and the segment edges of each nymph
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
Clean and mask the panel edges. These settings are a starting point; test on scrap first.
Slate blue, open top mask, 20 PSI, 0.3 mm needle, 15–20 cm away. Build a soft fade from the top edge down to roughly halfway.
Stone grey, pebble mask over the lower half, 18 PSI, 0.3 mm needle, 10 cm away. Fill the rounded pebble shapes with light even coats.
Moss green, boulder mask at the centre, 18 PSI, 0.3 mm needle, 10–12 cm away. Cover the boulder, then dust loose moss onto a few pebbles freehand.
Ochre, warm-stone mask, 15 PSI, 0.2 mm needle, 8 cm away. Touch the tops of the pebbles and add lichen patches on the boulder.
Umber brown, nymph mask, 15 PSI, 0.2 mm needle, 5–6 cm away. Fill the three bodies, then the legs, antennae and twin tails with short passes.
Cream, highlight mask, 12 PSI, 0.2 mm needle, 4–5 cm away. Tap glints onto stone tops and the edge of each body segment.
Let the paint cure for 24 hours at room temperature away from dust.
Seal with two light coats of clear fabric-safe sealer, 15 minutes apart, then cure another 24 hours 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
- Thick umber legs that blur into the pebbles. Drop the pressure and spray closer in short bursts.
- Moss green bleeding under the boulder mask. Burnish the mask edges and spray lighter coats.
- Ochre spread across whole pebbles, flattening the scene. Hit only the upper curve of each stone.
- Sealing too soon and clouding the colours. Wait the full 24 hours before the clear coat.
Tips
- Vary the grey pressure slightly from pebble to pebble so the riverbed does not look like tiles.
- Keep the slate-blue fade soft at its lower edge so the water seems to sit over the stones.
- Cut the nymph mask from a single sheet so legs and bodies line up exactly.
- Use the cream sparingly; a few bright points read as wet stone.
