Coco's tips
Lightly dust the 3D printed mold with cornstarch so the clay releases cleanly.
Coco bakes the plates at 255°F for 20 minutes. Always follow your own clay's temperature and time, and never leave the oven unattended.
Spray sealer: 3 light coats over the printed decal sheet, 10–15 minutes apart, somewhere well ventilated. Let the sheet dry at least 2 hours before using it.
Cut between the solid line and the dotted cutting line, soak each decal for about 15 seconds, then slide it off onto the plate.
Stay to the end of the video for the shortcut: ready-made 3D printed plates you can decorate right away (that's Part 3).
Safety: miniatures have small parts and are not food safe. Keep them away from young children and pets.
