# Five shapes are a whole language nobody signed > A blaze mark is paint on bark with no name attached. Five shapes carry an entire trail language, written by a stranger with a tin and a brush for another stranger they will never meet. August 19, 2026 · https://justog.club/stories/trail-blaze-marks Five marks, stacked in a key. One bar: carry on. Two bars, one above the other: turn soon. An inverted L: turn left. An L: turn right. An X: not this way. The paint looks brushed onto bark, the edges a little ragged rather than sharp. Nobody who painted these marks expects to meet the person reading them. ## What are these marks, and why do they look painted rather than printed? Because that's exactly what they are — paint applied by hand to a tree or a post, by somebody walking the route with a tin and a brush. A blaze is a small, deliberately simple shape repeated along a trail at intervals, and its raggedness isn't a design flourish, it's the honest residue of the method: a person standing at each marked point, painting the same shape freehand onto whatever surface is there, over and over, for the length of a route. ## Why do five plain shapes work better than words would? Because a shape holds up in weather and low light in a way that lettering doesn't, and it doesn't need the reader to share a language with whoever painted it. A single bar, two bars, an angle, an X — each is legible at a glance from a distance, through rain, at dusk, painted on bark that's never flat and never the same colour twice. Words would demand a sign, a fixing, upkeep. A shape only needs a tin of paint and a patch of bark, which is why the system survives in places nothing else does. [A road sign solves the same speed-reading problem with heavy plain lettering instead of a shape](/stories/road-sign-distance-plate) — a different medium built for the same glance. ## What's the real judgement in painting a set of blazes, rather than a rule to follow? How crude to make the mark, since crude is what makes it last. A neat, carefully stencilled blaze looks better on the day it's painted and worse a year later, once weather has started eating at its edges — a clean shape degrades into something ambiguous. A slightly rough shape painted by hand degrades into a slightly rougher version of the same shape, still readable, because the difference between a good blaze and a weathered one was never about precision to begin with. ## Does painting a blaze mark on a shirt raise a rights question at all? No — nobody owns a bar, an angle or an X painted on a tree, and no specific trail's exact placement is being reproduced here. The blaze vocabulary is a shared convention, developed and repainted by generations of volunteers across countless trails with no central authority and no licence required to use it. Where a named trail's own particular colour and shape combination matters to the wearer, that's simply a route they're referencing, not a mark they need anybody's permission to paint again. ## Does the same idea work for a group of walkers rather than one person? The blazes were never addressed to an individual in the first place, which is what makes them work for a group without any change at all. A blaze doesn't know or care who's reading it — it's aimed at whoever comes along next, on any day, alone or in a party of twenty. That's different from a mark left for one specific person to find; [a bunk list only ever describes one particular night's room of strangers](/stories/hostel-bunk-list), where a blaze describes the same fork in the path to every walker who will ever reach it. ## Isn't paint on a tree just proof somebody else walked here first? No — a blaze proves nothing about who came before. It's infrastructure, maintained for whoever comes next, not a record of who already passed. That's a genuine difference from a punch on a control card, which exists specifically to show that one named competitor stood at one exact point — [proof of an individual's presence, checked and timed](/stories/orienteering-control-card). A blaze has no name attached to it and keeps none; it's a public instruction, repainted by strangers, read by strangers, and it would still be doing its job even if nobody ever confirmed who used it. ## Do blaze marks print well? Yes — flat colour and simple geometric shapes are close to the easiest artwork this format offers. Keep the paint texture subtle: a slightly uneven edge reads as hand-brushed, but too much texture turns a clean shape into noise and the mark stops being legible at a glance, which is the one thing a real blaze can never afford to be. Two colours against the garment is usually enough — the shapes carry the meaning, not the palette. ## How do I get one made? Describe your key at [JustOG](/) — which shapes, which meanings, and how many marks in the sequence. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped. Designs other people have published are in the [shop](/shop). Somewhere ahead, on bark nobody photographed, the same five shapes are waiting for whoever walks there next.
