Just make a glue wash (glue + water) and brush the inside of the mason jars. Add glitter of your choice (I like silver) to the inside of the jars, and roll/spin the jar around until the glitter coats the sides. Let dry and add a tea light.
this is a diy that can spice up your room. just put all the pictures of you or anything you like and put them on the wall heart shaped to make it look clean and nice setup. then you got a wall full of pictures that are neat.
