DIY Trunk-or-Treat Car Magnet Kit With Cricut Print Then Cut

A trunk-or-treat display is easier to set up when its focal pieces are lightweight, reusable, and already mapped to the vehicle. This project converts selected ghosts, bats, eyes, stars, fangs, and game-day accents into rounded printable magnets for the smooth painted steel around a parked vehicle's rear hatch. Each piece has a number on its back and a matching paper placement map, so the scene can be installed quickly, counted before departure, and stored flat for the next event.

This is an original project plan based on standard Print Then Cut and printable-magnet workflows. Vehicle construction, paint condition, panel material, factory coatings, protective films, printer ink, printable magnet chemistry, optional clear coating, cutter calibration, weather, temperature, and handling can all change the result. Confirm every proposed panel and material with the vehicle and magnet-sheet makers, test a small rounded piece on a hidden maker-approved area, and edit only a duplicate working copy of the purchased artwork. The KleanKutChaos listing provides the decoration artwork; the featured KleanKutChaos file is the design source for this tutorial. This tutorial does not claim that the pictured combination was physically tested with the listing files.

What you’ll need

• Trunk or Treat SVG Bundle from the featured KleanKutChaos listing
• A parked vehicle whose maker permits temporary magnets on the exact smooth, clean, undamaged ferromagnetic steel panels selected
• Printable magnet sheets explicitly compatible with the exact inkjet printer and cutting machine
• Inkjet printer with fresh compatible ink; never use magnet material in a laser printer unless its maker explicitly permits it
• Cricut-, Silhouette-, or similar Print Then Cut machine with the specified blade and compatible mat
• Current cutting-machine software and a duplicate working copy of the purchased artwork
• Plain printer paper for test prints, full-size mock-ups, and the placement map
• Optional printable-magnet-maker-approved clear protective coating or laminate that remains cutter compatible
• Vehicle maker's approved wash solution, clean water, and several soft lint-free microfiber cloths
• Low-tack painter's tape for the paper placement rehearsal only—not for attaching decorations to the vehicle
• Ruler, flexible measuring tape, removable paper labels, pencil, and camera or phone
• Weeding tool or spatula, scraper, scissors, and bright task lighting
• Corner-rounding punch or scissors only if the magnet-sheet maker permits hand finishing
• Wax-free protective interleaving sheets and a rigid flat portfolio or document case
• Numbered inventory sheet, resealable pouch for small magnets, and permanent marker for the nonmagnetic backs
• Adult helpers for installation, removal, counting, and supervision during the parked event

How to make it

1. 1

   Confirm that the display can use magnets

   Read the vehicle maker's care and accessory guidance before buying materials. Identify only broad, smooth, undamaged painted ferromagnetic steel panels where temporary magnets are permitted; many vehicles also use aluminum, composite, plastic, glass, trim, films, wraps, or repaired areas that will not hold magnets or should not be covered. Never assume every body panel is magnetic.

2. 2

   Map every no-decoration zone

   With the vehicle parked, powered off, secured, and in a safe work area, mark generous paper-only exclusion zones around all windows, lights, reflectors, license plates, cameras, sensors, radar units, handles, emblems, vents, seams, weather seals, hinges, latches, fuel or charge doors, exhaust areas, tires, moving panels, and the lower road-debris zone. Keep the final magnets on uninterrupted maker-approved painted steel.

3. 3

   Test one small rounded magnet

   Clean and dry a hidden maker-approved test area and one sample magnet. Set the sample down flat without sliding it, leave it for the shorter of the vehicle or magnet maker's recommended test interval, then lift it straight off. Stop if it shifts easily, traps moisture, stains, scratches, dulls the finish, leaves residue, or reveals a non-steel panel.

4. 4

   Build a full-size paper rehearsal

   Measure the usable metal fields and print rough paper copies of the proposed ghosts, bats, eyes, stars, fangs, and football accents. With adult helpers, tape only the paper mock-ups where painter's tape is approved, then photograph the arrangement from straight behind and both rear corners. Confirm that every protected feature remains fully visible and usable.

5. 5

   Simplify a duplicate artwork file

   Keep the purchased files untouched and work from copies. Choose six to ten bold motifs, remove detached specks and very thin protrusions, enlarge narrow bridges, and give each shape a broad rounded outer contour. Avoid long tails, sharp tips, narrow wings, and tiny loose pieces that are harder to cut, count, and keep flat.

6. 6

   Create individual print-and-cut pieces

   Give each motif a solid printable background or offset border so it becomes one self-contained magnet. Flatten printable layers as required by the software, keep the cut line around the outside only, and size pieces to fit fully inside the tested steel zones. Do not join pieces into a long strip that must cross seams or curve around the hatch.

7. 7

   Make a numbered placement system

   Assign each magnet a number in the project file and repeat those numbers on a simple paper diagram of the vehicle. Put the visible number only on the nonmagnetic back after cutting, not on the artwork face. Record finished dimensions and quantity so every piece can be verified before the vehicle moves.

8. 8

   Calibrate and test on plain paper

   Run the machine maker's current Print Then Cut calibration if needed. Print the full sheet on ordinary paper from the software's official workflow, keeping the sensor marks untouched. Cut the paper test in the same session, check the outline around every motif, and correct scale or offset before using magnet material.

9. 9

   Print one magnet sheet at a time

   Load the printable side exactly as the magnet-sheet and printer makers specify. Use an inkjet only when required, feed one sheet at a time, and keep the sheet flat and free of dust. Complete printing through the cutting software's Print Then Cut flow so the registration marks retain the correct size.

10. 10

    Dry and protect the printed surface

    Lay the print flat in a clean supervised area for the material maker's full drying interval. If that maker permits a specific printable clear coating or laminate, apply it exactly as directed and verify that the added layer remains compatible with the cutter and sensor. Do not improvise with heat, thick epoxy, glitter, reflective film, or an unapproved spray.

11. 11

    Run a magnet-material test cut

    Place the sheet on the specified mat in the same orientation shown in software. Test a small motif with a curve, inside corner, and narrow bridge using the official printable-magnet setting as the starting point. The cut should separate the piece cleanly without deeply scoring the mat or shredding the printed face; adjust one setting at a time.

12. 12

    Cut, unload, and round every edge

    Run the final Print Then Cut job in the same software session. Unload only after the cut completes, then remove the surrounding waste before lifting each magnet with the recommended tool. If the material maker permits hand finishing, soften any remaining sharp corner with a rounding punch or smooth scissor curve; discard cracked, curled, or delaminated pieces.

13. 13

    Label and rehearse the complete kit

    Write the placement number on each nonmagnetic back, compare the set with the inventory, and arrange it on a steel practice board or flat table in diagram order. Pack the magnets flat between wax-free protective sheets, place small pieces in a labeled pouch, and keep the placement map at the front of a rigid portfolio.

14. 14

    Install only after the vehicle is parked

    At the event, park and secure the vehicle in its assigned space before opening the kit. Clean and dry the approved metal panels, then place each magnet flat without sliding or dragging it. Use the numbered map, keep every exclusion zone open, and have an adult recheck lights, plate, cameras, sensors, handles, windows, hatch movement, and all edges.

15. 15

    Remove and count before any driving

    At the end of the event, close off the work area from children, lift each magnet straight away from the paint, wipe away only moisture or dust using maker-approved care, and check the number off the inventory. Remove every magnet before closing a moving panel or driving—even for a very short distance—then store the fully dry pieces flat in their portfolio.

Practical finishing tips

• Large rounded ghosts, eyes, and stars are easier to see, cut, handle, and inventory than clusters of tiny bats or teeth.
• Keep one magnet per visual idea; connected pieces that span a body seam cannot sit flat and may be pinched when a hatch moves.
• Photograph the final parked arrangement and place a printout in the portfolio so helpers can recreate it without guessing.
• Use the same numbered inventory for setup and teardown; two adults counting independently can catch a missing piece before departure.
• Bring clean dry microfiber cloths and a weatherproof storage bin so sudden mist or dew does not get trapped against paint.
• If wind increases, the temperature changes sharply, or any edge begins to lift, take the entire display down immediately.
