Miniatures in a Jar - The Waterless Snow Globe. Easy to make and NOT one of those 'use a glow sitck' things. This one will light up when you want it to because the light really is a light! Tutorial - with photographs.
And of course, you can use them for your Christmas DIYs. You could turn them into a jar “snow ball”. Place a little tree and add a little white powder for the snowy effect. It’ll be a homey Christmas with these mason jar Christmas decors.
