**Short answer:** Yes, a wood burning pen marks a felt hat, but only natural felt is a fit: wool felt or fur felt. Synthetic felt is plastic, which melts and gives off fumes, and pyrography teacher Sue Walters advises burning only natural materials. Use a pen with a heat dial at its lowest setting, test under the brim and keep the tip moving.

Hat burning is pyrography on the brim and crown of a felt hat, done with the same pen used on wood. Three things decide the result: the fiber named on the hat's label, how low the pen can be set, and how steadily the tip moves. This page covers which hats sources accept and reject, the pen and tips, layout, the steps and how to tell the burn is done. Burn and Grain reads manuals and hat burning guides. It does not burn hats, so nothing here is a safety verdict on your hat.

## Which felt hats can take a wood burning pen?

Read the label inside the crown before anything else. Felt is a way of making fabric, not a fiber: it can be wool, animal fur or polyester, and these do not behave alike under a hot tip. The table sets out what the sources checked for this page say about each.

Hat pattern sellers do burn polyester hats: Cool Moon Designs suggests one for a first try, and in the same guide tells readers to stop if the material melts, hardens or gives off strong fumes. Pyrography references are stricter. Sue Walters' advice is to burn no plastics or acrylics, only natural materials. This site follows the stricter line, because synthetic felt melts and gives off fumes.

| Hat material | What sources say | This site's line |
| --- | --- | --- |
| Wool felt (label says 100% wool) | Natural fiber. Cool Moon Designs: can be burned, natural-looking result, costs more | Use it. Test under the brim first |
| Fur felt (felted animal fur) | Natural fiber. No source checked covers it separately | Treat like wool felt and test first |
| Polyester or acrylic felt, faux felt | Plastic. Sue Walters: do not burn plastics or acrylics, only natural materials | Do not burn |
| Wool and polyester blend | Cool Moon Designs: unknown synthetic blends may melt, scorch unevenly, smell strongly or make fumes | Do not burn |
| Faux suede, faux leather | Synthetic. Falls under the same warning as other plastics | Do not burn |

What named sources say about each hat material. No pen maker publishes a list of hat materials.

## Which wood burning tool and tips suit hat burning?

The pen needs a heat dial that goes low. A wire-nib burner has a dial on the power unit and heats and cools quickly. A solid-point pen with an inline dial also works and takes about 4 to 5 minutes to heat after each change. A fixed-heat solid pen runs at about 900 to 950 F by makers' figures and cannot be turned down, so it is the wrong pen for a hat. See the guide to [pens with temperature control](https://burnandgrain.com/best/best-wood-burning-tool-with-temperature-control).

For tips, start rounded: a writing nib or ball stylus on a wire-nib burner, a flow or ball tip on a solid pen. These leave an even line in any direction, which helps on a curved brim. The [wood burning tip chart](https://burnandgrain.com/tools/wood-burning-tip-chart) lists the skew as a nib that cuts slightly into the surface and the corner of a universal tip as one that digs in, so leave those until you know how the felt reacts.

## What heat setting for a wood burning pen on felt?

No pen maker publishes a setting for felt hats, and dial numbers are not degrees. The nearest maker figure is Walnut Hollow's zone list for its Creative Versa-Tool, which puts natural fabrics in zone 3 of 4, alongside paper and wood, and does not name felt or hats. So start at the **lowest dial setting** and raise it one small step at a time on the underside of the brim until a steady stroke leaves an even brown line.

Go by the mark, not the number. A line that is too pale can be darkened with a second pass. A scorched line cannot be taken back, and Cool Moon Designs gives the same order: begin low and build up. The [temperature chart](https://burnandgrain.com/tools/wood-burning-temperature-chart) explains dials and heat bands, but its figures are for wood, not felt.

Note: If the test line melts, hardens, smokes in an unusual way or smells strongly, stop. Cool Moon Designs lists these as signs to quit on that hat.

## Chalk layout, stencils and patterns for pyrography hats

Freehand drawing on a curved brim is hard, so mark the design before the pen is hot. Chalk is the usual tool on hat burning supply lists: a dressmaker's chalk pencil, or plain white chalk on darker felt. Keep the marks light, because whatever the pen does not cover has to brush off afterward.

A stencil gives repeatable shapes: hold or pin it flat to the brim, chalk through the openings, then lift it before burning. Cream, tan, camel and light gray hats show a burned line most clearly, and a very dark hat gives little contrast. The [stencil guide](https://burnandgrain.com/best/best-wood-burning-stencils) compares metal and adhesive sets.

## Steps: using a wood burning pen on a wool felt hat

These steps assume a wool or fur felt hat and a pen with a dial. The test under the brim matters most: it is what shows how this hat reacts.

1. Read the label inside the crown. Go on only if it says 100% wool, wool felt or fur felt. With no label, or with any polyester or acrylic listed, stop here.
2. Set up ventilation before heating the pen: an open window plus a fan or extractor that pulls smoke away from your face without blowing on the tip.
3. Mark the design in light chalk, or chalk through a stencil. Keep a first hat simple: clear outlines and larger shapes.
4. With the pen cold, fit a rounded tip. Set the dial to its lowest position and let the pen heat: about 4 to 5 minutes for a solid-point pen, far less for a wire nib.
5. On the underside of the brim draw 3 or 4 lines about 1 inch long at a steady speed with light pressure.
6. If the test lines are too pale, raise the dial one small step, wait and draw another row. Stop at the first setting that gives an even brown line.
7. Burn the design at that setting. Keep the tip moving, pull strokes toward you and lift at the end of each line. Never rest the tip on the felt.
8. Darken where needed with a second light pass instead of more heat, and keep your face away from the spot being burned.
9. Put the pen on its stand, switch it off and let it cool fully. Then brush the chalk off the felt.

## How to tell the pyrography on the hat is done

The burn is done when every chalk line has an even brown line over it from start to end, with no pale gaps where the tip skipped and no dark blobs where it paused. Once the hat is cool, check that the felt has not gone hard along the lines, since hardening is one of the warning signs Cool Moon Designs lists. Stop at an even mid brown: a black line means more heat, and a scorched spot cannot be repaired. How long the design lasts depends on the material, the depth of the burn, handling and weather, according to the same guide.

## Smoke and ventilation for hat burning with a pyrography pen

Burning felt makes smoke, and the standard rules for a pen apply: burn only bare, untreated natural material, with an open window and a fan or extractor that pulls smoke away from the face. A dust mask is made for sanding dust and does not filter smoke or gases. Cool Moon Designs adds that a desktop extractor does not replace fresh air.

Dye and any other treatment on a hat are not listed on the label, and no source checked for this page says what they give off under a hot tip. That is a gap, not an all-clear. If a hat smells strongly, smokes heavily or changes texture on the test line, do not burn it. More on smoke and masks is in [is pyrography safe](https://burnandgrain.com/blog/is-pyrography-safe).

Note: The tip and barrel cause burns, and the hand that steadies the brim is close to the tip. Use the stand and keep children and pets away.

## Quick answers

Short answers to the searches that lead here. Each one assumes a labeled wool or fur felt hat and a pen that has a heat dial.

- **Can you use a wood burning tool on a felt hat?** Yes on wool or fur felt, at the lowest setting that leaves a brown line. Not on synthetic felt, which melts and gives off fumes.
- **Which wood burning tool for hats?** One with a heat dial: a wire-nib burner or a solid pen with an inline dial. A fixed-heat pen cannot be turned down.
- **What should a pyrography hat burning kit have?** A pen with a heat dial, a rounded tip, chalk and a stencil. Check the fiber label of any hat sold with it.
- **Do pyrography stencils for hats work?** For layout, yes: chalk through the openings, lift the stencil, then burn the chalk lines.
