Opaque White is best used over Copic markers. Do NOT use marker tips over Opaque White. It has been proven that this will clog the pores of your marker tips and cause damage to them.
I've included some close-up shots from class samples where we apply Opaque White to our images. Adding that white can make all the difference where extra fine detail is needed.
Copic Colorless Blender to create faded drops on flowers then add a glint of white at the top of that drop to create a dew drop. Add a tiny shadow to the bottom of the drop with a coordinating superfine tip multiliner for a more realistic look.
Use Opaque White to make whites their whitest and add contrast back in. Adding dots of white on the sides of icicles helps to make the image appear to catch and reflect light. The lumps on the sides of the icicle make it look brighter or like glistening drops of water. The dots help to break up the lines and make them look more natural and realistic.
Add a few diagonal stripes of Opaque White to a window’s glass to make it appear to be more shiny.
Put snow caps on mountains. Add snow dust on pine tree branches, wreathes and roof tops. Add shiny glint to your balloons and fruit. Make your clouds just a little fluffier with a hint of the whitest white. Add some texture to your angel’s or dove’s (or chicken's?!?!) wings. Give your favorite man in the red suit some authentic old, gray hair.
I’ve tried substituting with Ranger’s Inkssentials opaque white pen and Claudine Hellmuth’s Studio blank canvas acrylic paint. While I love using those products on other projects, I'll turn to Copic's Opaque White whenever I need the best finishing touch for my Copic project. Experiment to see which you like best. Let me know what you think.
