Mix a clear white paint with fabric dye/food coloring until you get desired color. Paint the outside of the glass and let dry. You should have a nice color and you can seal that with varnish or polyurethane to prevent it from peeling. Use to store food products (stored in zip lock bags) in the kitchen, craft items, office supplies in the office, seeds for your garden etc. Do not use these by directly putting food inside of them for your protection. You could paint the bottoms one color and when dry paint the tops another color letting them drip down. I think this being done to a larger size container could be used as a centerpiece for a wedding since you could color co-ordinate them with different color schemes. You can do this with recycled items or it would really bring a dollar store vase up a notch… and don’t stop at glass – you can do this same process with plastic.
