Easter egg shells
If doing a design, draw it on your vase with chalk first. Brush with mod podge and apply your egg shells. Press the shells down so they are flat against the surface.
Let it dry for at least 15 minutes so the shells stay in place, then coat with a layer of Mod Podge. You may have to do more than one layer.
Once the shells are dry coat the entire flower pot with Mod Podge and let it dry.
Add a plant and admire your work.
