Do your coffee mugs need room for a message or maybe a little drawing? Then maybe you want to try a chalkboard mug. It's easy to do and you can change the message as much as you want.
Step 1: What you need
Not too much just this:
Krylon Chalkboard spray paint
Step 2: Mask off the mug
Take the tape and apply it wherever you don't want the paint to go. So here I'm going for a basic rectangle just to the right of the handle.
Step 3: Paint!
With the mug properly prepared, take it to a well ventilated area and spray it with the chalkboard spray paint. Apply 2-3 coats with at least 5 minutes between coats.
When it's all done you can remove the masking tape, but be sure to not use any chalk on it for at least 24 hours.
Step 4: Draw!
And that's it. Super easy to make and now you have an excuse to doodle in the morning. Enjoy!
