glass or cermaic jars (with or without lids is fine)
white spray paint
Gather supplies. I got my jars for about $1 each at my local thrift store
1. Spray paint the exterior of the jars. Do several coats until you can no longer see through the paint.
2. Paint the inside of the jars with acrylic paint.
3. With a pencil draw the shape you want for the chalkboard paint and fill it in.
That's it! You're done!
