New way for sharpies and dollar store plate! SANTAS COOKIES! Place in oven and let bake while heating up to 425 degrees. Then set timer for 30 mins, then let oven completely cool off before taking plate out. I've scrubbed and scratched and nothing came off. Still would recommend hand washing only.
cute idea- DIY Santa Plate and Mug (with "Naughty" on one side and "Nice" on the other). Create your design with a sharpie then once completely dry lightly paint a coat or two of ceramic/porcelain sealant over entire surface before baking.
