So, I bought a white case to color then cover with white. :)
After cleaning it with alcohol, I outlined the white plastic case with a gold metallic ink marker. Next, I filled in rich color with Spectrum Noir Markers. I found they blended nicely on the plastic.
I added some black and gold circles with round tops and inks. After everything dried, I spread a thin layer of white paint over the colored area and used a plastic tool to create texture. The arcrylic paint caused the alchol markers to blend and lighten.
I added a border and wrote the word "Faith" with a marker filled with high flow acrylic ink.
No blank space is safe at my house!
Take care and STAY POSITIVE!
