On a plain glass vase using tempera paints ( poster paint that is water based), I made a design on the vase with circles. With some added flowers ( these are silk) to the vase and a few Valentines that I made with PicMonkey and printed onto pink paper, I have a nice yet fast and easy project. I din't need to go to the store, I already had what I needed. Washing will easily remove the paint and it will be ready for another use.
You could use another type of paint of course that won't come off so easily such as glass paints or acrylics, but I wanted it to be a fast change out for next time.
Make sure your vase is very clean and free of finger prints. Find something to make a design with; I am using a finger rest for a pencil for my design but most any flat surface will work. You can use a paint brush too ;) Dip your tool of choice into the paint and work around the sides of the vase.
I started at the bottom and worked my way up. Then I used a new paint color and started over again. I made the circles closer together at the bottom of the vase and more scattered at the top. Let it dry. Add your flowers and hearts.
I could have placed a drawing or perhaps a coloring book page inside the vase and then traced the lines with a paint brush; wouldn't that be fun? The kids could do that too.
Change the paint color to suit your occasion. The vase is nice with out flowers but if you use real flowers just be careful not to get the paint wet as it will come off and will stain your furniture or table cloths. Perhaps place your flowers and water into a smaller container and slip that into the vase to keep it dry.
Another day for a different occasion, I can change up my design and colors and have a whole new look. Quick and easy.
