Nothing simplier like a cute Sharpie Marker personalized mug
It was my best friends 18th birthday so I wanted to give him something personal( MtG Rakdos Guild sign, something from Babylon 5 i think, Ranibowdash from MLP FIM, Elspeth also MtG and Lannisters sign and words :)
Clean your mug precisely.
Download the images you want to transfer on the mug. BUT flip them horizontal.
Redraw the pictures on the paper with a soft pencil. Take the pencil, flip the paper so the pencil-drawn picutre will be face down on the mug and scribble all over it to transfer it on the mug.
Take the black sharpie or a permanent marker and retrace the transfered image. Now give it som colour.
Put the mug into the oven on 180 degrees for 30 minutes. When it´s done DON´T TAKE IT OUT OF THE OVEN IMMEDARELY. Wait for the oven to cool down, mug will cool down with it. This is becuase you don´t want your mug to crack.
