Place a weave-pattern key where it remains visible while you hold the comb. Test your normal grip with a paper label before engraving the wood. A perfectly readable diagram on an empty tool can become useless when your thumb covers its first step.

The maker of this loom and comb project engraves herringbone instructions on the comb. The grip test below adapts that idea to a personalized precut wooden tool; it is not a claim that the maker reported an unreadable comb.
Follow one movement before choosing the engraving spot
Hold the comb as you would while packing a row of yarn. Move it through the working motion and notice where each finger rests. Then put the tool down in its usual place beside the loom. Both views matter: a key might be easiest to read while the comb rests, rather than while it is moving.
Use a short sequence that describes your own pattern. Define any symbol beside the sequence instead of expecting an unfamiliar abbreviation to explain itself. A miniature decorative chart is less useful than a few legible steps. Test the paper version against a short woven sample so the words correspond to the pattern you intend.
| Comb area | Visibility test | Design response |
|---|---|---|
| Thumb rest | Hidden during the working grip | Keep essential instructions elsewhere |
| Flat spine | Readable when laid beside loom | Place the step sequence here if it fits |
| Narrow tooth region | Crowded and subject to yarn contact | Avoid a long instruction line |
| Reverse face | Requires turning the tool | Reserve for a name or secondary note |
Match the key to the actual weaving setup
Your instruction sequence should correspond to the warp spacing chosen for the yarn. A diagram drawn for closely spaced threads may become confusing if you weave through alternate slots. On a different tool, rigid-heddle slot and eye threading is a separate arrangement; do not assume its instructions describe a frame loom.
When storing spare yarn with the comb, a bobbin thread-end retention test helps keep the working yarn ready without repeatedly rewinding it. Keep all yarn away from the laser while marking the wooden comb.
The TYVOK P2 can be considered for a small mark on known laser-compatible precut wood. Confirm the flat marking area, installed module and fixture support before processing. This is personalization, not a promise to cut comb teeth. Work with extraction and the prescribed eye protection, supervise the operation, and inspect for roughness before letting the finished surface touch yarn.
Should the key face my dominant hand?
Test the actual grip rather than choosing from handedness alone. Some makers change hands or set the comb down between rows. Put the most important steps where they are readable in your own working position.
Can I engrave deeply so the instructions last longer?
Depth alone does not establish durability and may leave a rough surface. Prefer a readable tested mark; inspect and finish the tool appropriately without erasing fine lettering or creating yarn snags.
