Welcome to Lesson 3 of the HTVRONT E15 Embroidery Machine tutorial series. In Lesson 2, we completed your first garment embroidery project. Today, we'll learn how to embroider your first hat with the E15 15-needle embroidery machine — the most requested skill for anyone running a small custom apparel business.
Cap embroidery is genuinely different from flat garment work. Hats are curved, multi-layered, and made from stiffer materials, so they require a dedicated Cap Hoop, a Cap Driver, and a slightly different hooping technique. By the end of this lesson, you'll have completed a full hat embroidery project and be ready to add caps to your product lineup.
Let's get started.
Key Takeaways
Remove the Garment Hoop bracket first — the Cap Driver mounts on the same X-axis mounting points.
Select Cap Hoop on the touchscreen before installing the Cap Driver — the machine needs to know the correct frame type.
Cap embroidery runs at a controlled speed — start at 500 SPM for clean, even stitching on curved surfaces.
Alignment is everything — use the red laser point to center the design on the cap's front seam.
Use cap-specific designs — not every flat embroidery file will work well on a curved, multi-layer cap front.
Accessories You'll Need
Before we begin, prepare the following accessories. All of these are included in the E15 standard package or available as add-ons:
Cap Hooping Station — holds the cap hoop steady while you position the cap
Cap Driver — replaces the garment hoop bracket on the X-axis
Cap Hoop — curved hoop designed specifically for cap fronts
Cap embroidery stabilizer — provides structure for the curved cap front
Blank cap — a plain, unstructured or structured cap for your first project
Today's tutorial includes four parts:
Removing the Garment Hoop
Installing the Cap Driver
Hooping the Cap
Embroidering your first cap
Part 1: Remove the Garment Hoop
Let's begin by removing the Garment Hoop. Turn on the machine. When the screen displays the "Find the Machine Original" prompt, tap OK to confirm. The machine will complete its home positioning sequence.
Next, remove the four knobs from the Garment Hoop Bracket. Set the bracket and knobs aside in a safe place — you'll need them again for your next flat garment project.
Pro Tip: Store the Garment Hoop Bracket, adapter block, and knobs in a labeled bag or box so you can quickly switch between cap and garment setups in the future.
Part 2: Install the Cap Driver
Now, let's move on to Part 2: Installing the Cap Driver. First, tap Frame Select on the touchscreen. Select Cap Hoop, then tap ☑️ to confirm. This tells the machine which frame type is now installed so it can calculate the correct stitch boundaries.
Next, slide the Cap Driver into the rotary hook arm. Push it fully into position until it is seated securely.
Tighten the two mounting knobs counterclockwise to secure the Cap Driver.
Note: Support the knob from underneath, align it with the threaded hole, then tighten it securely. If you don't support the knob, the thread can cross and jam.
Align the Cap Driver with the X-axis mounting holes, then secure it with the two mounting knobs.
Part 3: Hoop the Cap
Next, let's prepare the cap hoop. This is the most hands-on part of the process — getting the cap perfectly positioned on the hoop determines how well your design stitches out.
First, secure the Cap Hooping Station to the edge of your table.
Attach the Cap Hoop to the Cap Hooping Station. Align the groove on the top, then secure the hoop in place.
Insert the cap stabilizer into the hoop slot.
Fold the sweatband outward. Center the cap on the hoop.
Position the metal retaining strip of the cap frame along the seam between the cap brim and the front panel. Lock the clips to secure the cap in place.
Pro Tip: The cap should be snug but not stretched. If the fabric is too tight, the design will distort when the hoop is removed. If it's too loose, the stitches will be uneven. Aim for a firm, wrinkle-free front panel.
Press both side locks down and remove the cap hoop from the hooping station.
Next, install the hooped cap onto the machine. Keep the brim horizontal and attach the cap to the Cap Driver.
Rotate the cap to align the positioning grooves. You will hear a click from both sides when the cap is locked in place.
Part 4: Embroider Your First Cap
Let's start your first cap embroidery. The workflow mirrors your garment project from Lesson 2, with a few cap-specific steps added.
1. Upload a Design from USB Drive
Insert the USB drive with your cap embroidery design into the machine. Tap the USB icon at the top, then select Upload Design.
Note: Use designs created specifically for cap embroidery. Flat designs are stitched in a linear order that assumes a flat surface — they can distort or pull on a curved, multi-layer cap front.
2. Edit the Design
Choose your cap design and import it to the design library. Tap Pattern Select and choose the cap design you just uploaded. The machine will open the Design Edit interface. Adjust the design as needed, including rotation or mirroring.
Make sure the design is positioned inside the blue hoop area on the screen.
3. Confirm the Hoop Type
Make sure the hoop type is set to Cap Hoop. Align the red laser point with the cap's center seam. Make sure the design is centered on the cap.
⚠️ Alignment matters most: A cap design that's even slightly off-center is immediately noticeable — the logo will look crooked on the finished hat. Take an extra 30 seconds to verify the laser point sits exactly on the center seam before proceeding.
4. Set Thread Colors
Next, tap Color Setup. Adjust the design colors based on your preference — you can reassign which needle handles each color in the design.
5. Use Pattern Trace
Next, use Pattern Trace to check the embroidery area. The machine will trace the design's outer boundary to confirm it fits within the cap hoop and doesn't overlap the brim or seams.
6. Start Embroidery
For your first cap embroidery project, we recommend setting the speed to 500 SPM.
After confirming all settings, switch the machine to Embroidery mode. Press the Start button to begin embroidery.
Watch the first few stitches: Stay near the machine during the first minute of stitching. If you see the needle struggling, the cap shifting, or any unexpected pulling, press the Emergency Stop button and re-check the hoop setup. Catching a problem early saves the cap.
Removing the Finished Cap
After embroidery is complete, press both side locks and remove the cap hoop from the Cap Driver. Rotate the brim until it is parallel with the X-axis, then remove the cap completely.
Finally, release the locks on the Cap Hoop and remove the cap.
Congratulations on completing your first hat embroidery project with the HTVRONT E15! Now you're ready to create more personalized hat designs and add cap embroidery to your business offerings.

Conclusion
You've now completed your first hat embroidery project on the E15 embroidery machine. From removing the Garment Hoop and installing the Cap Driver to hooping the cap, aligning the design with the laser point, and running your first stitch-out — you've mastered the full cap embroidery workflow.
Take a close look at your finished cap. Is the design centered on the front panel? Are the stitches clean and even across the curved surface? Is the tension balanced between the upper thread and bobbin? If everything looks good, you're ready to start taking cap orders — the highest-margin product category for most small embroidery businesses.
In the next lesson, we'll cover how to maintain and troubleshoot your E15 embroidery machine. For now, practice what you've learned — run a few more cap projects, experiment with different stabilizer weights, and get comfortable switching between cap and garment setups.
Do I need to remove the Garment Hoop before installing the Cap Driver?
Yes — the Cap Driver and the Garment Hoop Bracket mount to the same X-axis mounting points. You can't have both installed at the same time. Remove the four knobs from the Garment Hoop Bracket, store the bracket and knobs safely, then mount the Cap Driver in its place. Switching between them takes only a minute once you're familiar with the process.
Why should I select "Cap Hoop" on the touchscreen before installing the Cap Driver?
The machine needs to know which frame type is installed so it can calculate the correct stitch boundaries. If you select the wrong frame type, the machine may move the design outside the actual embroidery area, causing hoop collisions, needle breaks, or damage to the cap. Always set the frame type on the touchscreen before you start a new project.
Can I use any embroidery design on a cap?
No — use designs created specifically for cap embroidery. Flat garment designs are stitched in a linear order that assumes a flat surface, which can distort or pull on a curved, multi-layer cap front. Cap designs are digitized with the correct stitch sequence, density, and pull compensation for curved surfaces. Using flat designs on caps often results in puckering, misalignment, or thread breaks.
Why should I start at 500 SPM for cap embroidery?
Cap embroidery runs at a lower speed than flat garment work because of the cap's curved, multi-layer construction. At 500 SPM, the needle has more time to penetrate the fabric cleanly, and the cap has less chance to shift in the hoop. This is especially important on your first project while you learn how the cap behaves under the needle. Once you're confident, you can gradually increase the speed up to the machine's cap embroidery maximum of 850 RPM.
How do I know if the cap is hooped correctly?
The cap front should be smooth, wrinkle-free, and firmly held — but not stretched. If the fabric is too tight, the design will distort when the hoop is removed. If it's too loose, the stitches will be uneven. When positioning the cap, center the front panel over the hoop, fold the sweatband outward, and make sure the metal retaining strip sits exactly along the seam between the brim and the front panel.
Can I embroider a structured cap (with a stiff front panel)?
Yes — the E15 Cap Hoop and Cap Driver are designed to work with both structured and unstructured caps. Structured caps have a stiff buckram layer inside the front panel that keeps the shape. They typically produce the cleanest embroidery results because the fabric doesn't shift. Unstructured caps (soft, floppy fronts) require a bit more care during hooping to avoid wrinkles, but they work well too.
