Senior Gift Ideas-DIY Sharpie Mug- the RIGHT way! Use OIL based Sharpies (you can use stickers as a stencil/outline). When it looks the way you want put it in cold oven, set to bake at 350 and leave for 30 mins
Paint pen or oil based sharpie,allow them to dry for at least 24 hours. Once 24 hours has passed place them in a cold oven (this is important! you want them to heat up with the oven). Turn the oven to 400 degrees and set a timer for 40 minutes.
